摘要：

Durene (1,2,4,5-tetramethylbenzene) dissolved in n-hexane was photoionized by 35-ps light pulses at 266 nm. Transient absorption at 1064 nm arising chiefly from geminate electrons was detected and used to monitor the recombination of the electron-cation pairs produced by two-photon ionization. An excellent fit to the recombination kinetics at 208 K was obtained by assuming that the distribution of initial electron-cation separations was of the form r2EXP = r2/(2L3) exp(-r/L) with a mean radius 3L = 5.7 nm.
