摘要：

Diphenyldiazomethane radical anion (Ph2Cn2-.) has been generated by pulse radiolytic reduction of diphenyldiazomethane (Ph2CN2) in acetonitrile. Subsequent pulse laser excitation within the electronic absorption band of Ph2Cn2-. (lambda(max) = 370 nm) results in a strong irreversible bleach of the absorption signal and a simultaneous appearance of a secondary absorption band (lambda(max) = 330 nm). The secondary transient is attributed to diphenylmethyl radical (Ph2CH) formed by protonation of diphenylcarbene radical anion (Ph2C-.) within the laser excitation pulse.
