摘要

The present study examined the electronic dynamics of 4,5-dimethoxy-2-nitrobenzyl acetate after π-π* excitation. Pump-probe measurement using a near-ultraviolet sub-10 fs pulse laser revealed that the lifetime of the S * (π-π*) state is 500 fs after photoexcitation to produce the S * (n-π*) state and that the lifetime of the S * (n-π*) state is 1000 fs. By studying different alpha substituents, the lifetimes of the S * (π-π*) state and the S * (n-π*) were found to be independent on the alpha substituents.
