Abstract

A setup for measuring femtosecond transient absorption in the gas phase is reported. The apparatus is based on a 1 kHz amplified Ti:sapphire laser system and measures gas-phase transient absorption using a shot-to-shot normalization scheme with background subtraction. We have used this setup to examine the wave packet dynamics of the I 2 B state in the vapor phase as a benchmark. The results are consistent with those reported by other groups using indirect transient absorption techniques.
