摘要

我们提出了振动选择性泵探针测量喷气冷却中性儿茶酚(1,2-二羟基苯)的第一电子激发态(pp*)寿命。0-0跃迁的寿命非常短(7 ps)，这是由计算的小pp*/psigma*间隙所证明的。然而，意味着更高的面外振动水平的寿命更长(~11 ps)。这强调了面外振动在pp*/psigma*耦合中的作用，不仅在其性质上，而且在量子数量上

Unusual behavior in the first excited state lifetime of catechol

We are presenting vibrationally selective pump-probe measurements of the first electronic excited-state (pp*) lifetime of jet-cooled neutral catechol (1,2-dihydroxybenzene). The lifetime of the 0-0 transition is very short (7 ps) as rationalized by the small pp*/psigma* gap calculated. However the lifetimes implying higher out-of-plane vibrational levels are longer (~11 ps). This emphasizes the role of the out-of-plane vibration in the pp*/psigma* coupling not only in its nature but also in the number of quanta
