摘要：

The photodissociation of tetraphenylhydrazine and tetratolylhydrazines has been investigated by picosecond transient absorption and fluorescence measurements. We have confirmed that the formation of the product radical is observed in the tens of picoseconds time region and that the geminate radical recombination is not observed in the time region of 10 ps to several nanoseconds. The slow N-N bond rupture occurs in the fluorescence state of tetraarylhydrazines, which can be explained by the slow internal conversion from the fluorescence state to the dissociative state.
