Diphenylbutadiene in supersonic jets: Spectroscopy and picosecond dynamics

Abstract

The picosecond dynamics and one- and two-photon excitation of jet-cooled diphenylbutadiene are reported. An A_g^* state is found to lie below the dipole allowed B_u^* state. Isomerization and/or other non-radiative processes are important above a threshold of 1050 cm^(−1) excess energy. Results are compared with those previously obtained for stilbene.
