β¦ Synopsis
Force field parameters have been developed that reproduce the triplet state ab initio geometries of two ketones. Transition state energies and geometries have been computed for a variety of Norrish Type II reactions. A correlation has been found between overall reaction and transition state strain energy.

Methyl-a-keto-octanoate undergoes a Type II reaction to give pent-l-ene and photophysical measurements show that this and the Type II reactions of a-ketoacids occur, contrary to previous claims, from the excited singlet state.
## Abstract QM/MM methods have been developed as a computationally feasible solution to QM simulation of chemical processes, such as enzymeβcatalyzed reactions, within a more approximate MM representation of the condensedβphase environment. However, there has been no independent method for checking
