Abstract

The interactions between C=C and C=O double bonds in
several unsaturated ketones have been studied by comparing
MIND0/2 caloulations wiith ionisation potentials determined by
photoelectron spectroscopy (PES). With one exception (norbornadienone)
the direct through-space interactions in conjugated .ketones
appear to be negligible, the double bonds couple hyperoonjugatively
via the intervening a bonds. This kind of approach should prove
useful for studying other long range interactions.
