摘要: The polarizations of the transitions to lowest nπ* and two ππ* phthalaldehyde have been measured relative phosphorescence by method photoselection. polarization 10‐methylene anthrone state 1La 1Lb states, which are split exciton interaction, has also determined. Molecular orbital calculations, spin‐orbit coupling, considerations experimental results indicate that T1← S0 transition is polarized along carbonyl carbon‐oxygen bond (Z axis). Application Platt's spectroscopic moment theory system, considered as weakly interacting benzene units perturbed formyl vinyl substituents, does not account for observed in region a Z‐polarized moment. curve explained on basis states inter‐ring ex...
