Abstract
The equation for the calculation of absorption maxima for conjugated heteroenoid compounds has been extended to include a number of α-benzoyl-trans-benzalacetones and ethyl α-benzoyl-trans-cinnamates and has been used to assign configuration to the α-cyano-trans-benzalacetophenones. The method for calculating the substituent constant, D, has been refined to give more accurate values.Keywords
