✦ Synopsis

The resonance Raman spectrum of all-trans-diphenylbutadiene in its lowest exited St state exited in resonance with the S1 + S,, absorption band at 650 nm in non-pohr solvents is reported_ Three vldrational bands at 1572,1481 and 1165 Cm-l are observed. A possible assignment of the the 1481 cm-l the lowest S, state being of "Ai-band to the C=C double-bond stretching mode may support symmetry_
