Abstract
A method is described for the analysis of non-bonded forces in crystalline organic compounds. It is developed by reference to the photoreactive compound 2-benzyl-5-benzylidene-cyclopentanone (BBCP) and its derivatives, but it is of general validity. The approach is valuable for predicting the structural consequences of substitution at different positions in a given molecule; this ability is of importance in predicting the reactivity of organic solids.
