The degree of circular polarization gin electronic transitions of chiral molecules is a measure of the ratio of the magnetic and electric dipole transition moments. From theory an upper bound for lgl as a function of dipole strength D can be found. This offers the possibility to distinguish %x\* fro

✦ Synopsis
A consideration of the electronic coupling part of the non-radiative rate constant shows that this factor is importsnt in determining complmtive features of radiationless transitions in some heterocyciics. Some symmetry ruler for radiationless processes nrr? discusSed, and simptc MO theory is used to make quafitative comparisons of non-radiatitz coupling of the phosphoresant state into the ground state of azincs.

We have made single crystal ODOR and phosphorescence studies of the T1 state of 2-indanone. It was shown that the T, state of 2-indanone is very similar to that of the 'nd state cyclopentanone\_ The well resolved phosphorescence specl m indicates that the 3nd 2-indanone has a distorted structure\_ A
