Wavepacket motion and ultrafast electron transfer in the system oxazine 1 in N,N-dimethylaniline

Abstract

Femtosecond experiments on the oxazine 1 in N,N-dimethylaniline electron transfer system have been performed with a cross-correlation width of less than 18 fs. The experiments exhibit two different ultrafast absorption changes: a fast decay of the transmission occurs on the 30–80 fs timescale. This feature is assigned to an extremely fast electron transfer. Superimposed on these kinetics, assigned to the electron transfer, are strong oscillations arising from the wavepacket motion on the ground and excited state electronic surfaces with frequencies of up to 18 THz.
