Chemshell gaussian
WebQM/MM geometry optimization with Chemshell and ORCA. QM/MM geometry optimizations in Chemshell are documented in the Chemshell manual. Using ORCA as the QM code in QM/MM calculations just means that you have to modify the qm_theory part. As always in QM/MM, setting up the system and the MM region is the complicated part. Web*gzmt – Start of geometry input in the form of Gaussian Z-Matrices. 0V1 – charge and spin multiplicity of your molecule. Spin multiplicity = 2S+1 where, S is the total electron spin of the molecule. If a molecule has 1 unpaired electron, S=1/2 and the spin multiplicity=2 * –End of coordinate definition. 3. Close the input file. 4.
