Abstract

Underlying the completely‐optimized S~0~ and T~1~ molecular geometries of isomeric terphenyls the corresponding theoretical vibronic T~1~ → S~0~ ‘line’ spectra calculated within the CONDON approach, are presented and compared with the experimental phosphorescences. The influence of possible conformations on the vibronic spectral behaviour is studied theoretically. The DUSHINSKY effect is found to be most important to the T~1~ → S~0~ phosphorescence of m‐terphenyl. An analysis of the spectroscopically relevant vibrational modes is given.
