Abstract

Abstract Picosecond excitation of the 28 250 cm −1 overtone band in the 1(π,π *) manifold of trans-azobenzene yields an emission spectrum with a prominent S 2 → S 0 fluorescence band in addition to an S 1 → S 0 component from the 1(n, π *) manifold. The S 2 → S 0 fluorescence decay time at 420 nm is ⪷ 5 ps.
