## Abstract __Ab initio__ molecular orbital theory is used to examine the effect of substituents on bond lengths in monoโ and disubstituted methanes. The relative importance of electrostatic and orbital interaction terms are assessed. The results suggest that for substituents (X) which show powerfu
A study of the photoreactions of some triarylfurobenzodioxin derivatives has shown that the outcome is dependent on the type and position of the substitution on the9a-aryl group. A wavelength dependence is also reported.
