Theoretical vibronic T,+Sc "line" spectra of the isomeric phenylnaphthalenes, calculated within the Condon approach on the basis of completely optimized So and T, molecular geometries, are presented and compared with experimental phosphorescence spectra. The theory-experiment comparison is satisfact

β¦ Synopsis
The calculated vihronic strtrcture of the phosphorescence of biphenyl is presented and compared with the esperimental spwtrum. .4n sssigm~ent of the vibronic transitions for the msin peaks is @zn. The comparison between theory and esperimcnt is 53tisf;lctory.

The calculated vibronic structure of the S-S, absorption and fluorescence band of benzo(k)-fluoranthene IS presented and compared with the experimental spectra. An assignment of the vibromc transitions is given for the main peaks. The comparison turns out to be satisfactory.
The absorption spectra of biphenylJl lo and -dlo crystals in the region of the lAlg + lBag, lBzu transitions are interpreted in terms of vibronic coupling of the two closely spaced electronic states by six bl, vibrations.
