5. 170 You can specify a value after the sign separated by a space If this value is different from the current value of the coordinate according to the geometry it will be used as a dynamic constraint For example consider the following zmat section for water in which the distance between the two hydrogen atoms is 1 507 angstroms amp zmat o hi o 0 95 h2 o 0 95 hl 105 amp Now suppose you want to optimize the geometry subject to the constraint that the distance between the hydrogen atoms is 2 0 Then you would add the following coord section amp coord hl h2 2 0 amp You can specify a variable after the sign separated by a space The values that the variable takes must be given in a zvar section The following example defines a variable HH as the distance between Hl and H2 amp coord Hl H2 HH amp For torsional dihedral angles you can fix the natural torsional angle by specifying the bond about which rotation can take place followed by nt or NT no spaces as in the following example amp coord C1 C2 fint amp The natural torsional angle is the average of all the torsional angles that can be defined using this bond and the atoms bonded to either end of it The main use of the natural torsional angle is in coordinate scans where it permits an averaged torsional potential to be obtained See Section 4 4 3 on page 87 for more information Harmonic constraints can be set on the Cart

7. When Maestro checks whether a symmetry operation produces an equivalent structure the coordinates of the two structures only have to be the same to within a prescribed tolerance that is each pair of symmetry related atoms is within a distance specified by the tolerance The value of the tolerance can be specified in the Tolerance text box and is 0 04 by default This value ensures that the highest symmetry is found in most cases By changing the value and clicking the Find Point Group button you can determine whether there is a lower or higher symmetry point group that approximately describes the structure and use that group to symmetrize the molecule instead of the default The tolerance is also used when the molecule is symmetrized After translation and rotation the coordinates of the atoms are adjusted to reflect the symmetry group accurately The maximum displacement permitted is the tolerance specified A large tolerance yields the highest symmetry but may cause the coordinates to be changed significantly A small tolerance may yield a lower symmetry but results in smaller coordinate changes The main Jaguar programs use a small tolerance 1 0 x 10 bohr which should result in molecular energy changes of microHartree or less You can turn the use of symmetry off in the Molecule tab For methods such as GVB LMP2 GVB LMP2 and for some properties such as IR intensities or hyperpolarizabilities symmetry is not yet implemente

15. As we have discussed extensively in several publications empirical optimization of parameters is absolutely necessary to obtain accurate solvation free energies from SCRF calculation no matter what the level of electron correlation Continuum solvation methods do not rigorously treat effects at the dielectric boundary which therefore must be adjusted to fit experiment For neutral species we have optimized parameters both dielectric radii and surface tension terms by fitting to experimental gas to water solvation free energy data for small molecules Agreement to within a few tenths of a kcal mole can be obtained for most functional groups However parameterization of the model for ionic species in this fashion cannot lead to high levels of accuracy because there are large error bars on the experimental data typically 5 10 kcal mole An error of 5 kcal mol in the solvation free energy that was not systematic would lead to huge errors in pK calculations This is because in determining the pK there is a cancel lation of two very large terms the gas phase deprotonation energy which favors the proto nated state and the solvation free energy which favors the deprotonated state Errors in either term therefore can be a small percentage of the total energy but lead to very large errors in the resulting calculated pK To overcome this problem the parameters for ions are fitted directly to experimental pK data If the gas phase quantum chem

The second line has two integers The first integer gives the number of dealiasing function sets provided for each atom type each set is used for a particular grid during the calculation The ordering of the sets used for each grid type is determined by the parameters named dcoarse dmedium and so on which are specified in the gen section of the input file By default the coarse grid is listed first then the medium fine ultrafine and gradient grids in that order The second number in the second line gives the number of ranges described in each of these dealiasing function sets The ranges correspond to particular RwR blocks for the calculation One of these ranges is the long range basically covering the whole molecule another is the home atom range which actually only includes the relevant atom itself and the rest are increasingly large neighbor ranges The number of ranges should currently not exceed 10 The sample file s second line indicates that for each basis set five dealiasing function sets are spec ified for each atom and that each of these sets contains dealiasing functions for a total of six ranges the long range functions the functions for the home atom and the functions for four other neighbor ranges The distances defining the neighbor ranges are set in the next line of real values in units of bohr Note however that generally only the third neighbor range is actually used The first distance specifies that if the ba

Jaguar 7 5 User Manual Chapter 3 Options We advise using GVB LMP2 primarily for single point energy calculations since Jaguar cannot compute GVB LMP2 atomic charges or analytic gradients For best results with GVB LMP 2 first run your calculations with the 6 31G basis set then change the basis set in the restart file to cc pWTZ f and restart the job See Section 6 5 on page 144 for a description of how to restart jobs This procedure will generally be significantly faster than running a GVB LMP2 cc pVTZ f job from scratch 3 8 SCF Settings The SCF tab includes various settings that control the type of calculation and how the calcula tion is performed including the accuracy level the convergence method and criteria and the orbital symmetry and localization 3 8 1 Accuracy Level Jaguar can use integrals evaluated on a grid with the pseudospectral method and fully analytic integrals The grids used for various SCF iterations and the accuracy with which parts of the calculation are done greatly affect the timing and sometimes the accuracy of the entire calcu lation You can adjust the grids and the set of cutoff values determining these factors using the Accuracy level option menu For more information on grids and cutoffs see Section 9 4 on page 257 and Section 9 5 on page 260 The default Quick setting allows fast calculations to be performed using several different pseudospectral grid types and cutoffs that should

The binding energy extrapolated to the basis set limit is printed last For especially weakly bound systems it occa sionally happens that the energy obtained with the cc pVTZ f basis set is slightly lower than that obtained with the larger cc pVQZ g basis set In this situation the usual two point basis set extrapolation formula cannot be used so the energy is instead corrected using a simple linear correction of the LMP2 cc pVQZ g energies to the CCSD T reference energies The output file clearly indicates when this has happened The binding energy will still be quite accurate to within 0 5 kcal mol when compared to the CCSD T energy 10 243 distributed scan py This script splits up a 1D or 2D scan job into multiple jobs that can be distributed over multiple processors and is used automatically by Maestro for such a job The script accepts a single input file that defines the scan job The processors are specified using the HOST job control option see page 38 of the Job Control Guide The results are collated into a single output when all jobs have finished 1 This is likely due to the fact that the BSSE corrections are calculated only for the Hartree Fock part of the wave function rather than for the full LMP2 wave function which would be more expensive The error in this approximation amounts to a few tenths of a kcal mol Jaguar 7 5 User Manual 291 292 Jaguar 7 5 User Manual Chapter 11 Troubleshooting Naturally
