Abstract

Transient absorption spectra and kinetics of the photodissociation of CH₂I₂ in solution were recorded with a femtosecond laser system. Excitation of CH₂I₂ in the spectral range 300-350 nm mainly results in the formation of CH₂I + I(²P_3/2). Transient absorption spectra of CH₂I₂ in acetonitrile as solvent at different delay times from 0 fs to 15 picoseconds are shown in the figure. At t=0, the transient absorption spectrum exhibits two bands at 500 and 700 nm.
