N2  - Spectroscopic studies on a series of methoxycarbonyl-substituted &#946;,&#947;-unsaturated bicyclic ketones show a decrease in n-&#960;* transition enhancement in the bicyclo[2,2,2]octadienone derivative relative to that observed in the correspondingly substituted bicyclo [2,2,2] octenone. Crystallographic studies on the related derivatives have been carried out in an attempt to ascertain the influence of ground- state molecular geometry. The results show the detectable difference in geometry to be small and suggest the change in enhancement to be, more likely, a spectral repercussion of homodiene conjugation.
