Effect of the vibrational excitation on the non-radiative deactivation rate of the S1 state of p-cresol(NH3) complex

Mostrar todas las versiones(2)

The effect of the CH3 group on the lifetime of the S1 state of the p-cresol(NH3) complex was investigated by means of REMPI, LIF, DF spectroscopy and ab initio calculations. At variance with PhOH(NH3) for which vibrational-mode specificity was reported, the lifetime of the S1 state of the p-cresol(N...
