Gamess Tutorials. Hello and welcome to the tutorials of GAMESS.
This is a simple web site where you could find help to understand what we can do with GAMESS and also useful tutorials to learn how to create input files and to interpret the output files of GAMESS. This module will introduce you to how quantum mechanical calculations can be used to investigate chemical processes. An online portal to the program GAMESS is used to run calculations and explore commonly used methods for computing. Examples are given for several molecules that are in the environment.

QM class. Gamess. In a previous post I discussed the TSs of acetamide hydrolysis and hydrolysis of a related amide (3).
I have already made a post on how to find the TS for 3, and in this post I summarize the two ways of finding the TS for acetamide hydrolysis, that I describe in Chapter 5 of the book (where you can find many more details). To start, I use Avogadro to build the geometry shown in Figure 5.32a and use it to construct the input file for an optimization with 4 constrained bond length. The values for the constraints are taken from a paper.
Figure 5.32b shows the equilibrium geometry obtained with GAMESS, after 17 steps. Based on this geometry GAMESS finds the TS in three steps.
