摘要: Ultrafast photo-excitation dynamics of N-benzyl 2-methyl-4-nitroaniline was studied with femtosecond time-resolved absorption spectroscopy. The photo-induced spectrum found to consist three transient components different decay times. A 260 fs-decay time stimulated emission appeared during a geometrical relaxation from charge-transfer excited state geometrically relaxed state. following energy the completed within 680 fs. Third 2.6 ps reflected cooling process hot electrons in ground potential.
