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