Abstract
Out‐of‐plane vibrations which may be effective in vibronic coupling between and states of aromatic carbonyl compounds are investigated, and the probable importance of these vibrations in radiationless transitions is demonstrated through the dependence of vibrational features, quantum yields, and lifetimes of phosphorescence upon deuteration of the COR (R is H or an alkyl) group, nature of solvents, and molecular structure (e.g., ketones versus aldehydes).
