Abstract
The rotationally resolved excitation spectrum of the 0(0)0 band of the S1<--S0 transition in 2H-benzotriazole, at 286.4 nm, is obtained by u sing laser-induced fluorescence spectroscopy in a molecular beam. From this pure b-type spectrum, the rotational constants in the ground sta te and the electronically excited state are determined. The rotational lines are strongly broadened due to the short lifetime which is deter mined to be around 1.1 ns.
