Laser flash photolysis (LFP, XeCl, 308 nm, 20 ns) of phenyldiazomethane (PDM), o-tolydiazomethane (TDM) and mesitydiazomethane (MDM) produces phenylcarbene (PC), o-tolycarbene (TC) and mesitylcarbene (MSC), respectively. Transient spectra of PC and TC could not be detected in pentane at ambient temp

The photolysis of phenylazotriphenyl methane (PAT) in dichloromethane and acetonitrile solution at and at 23Β‘C results in the j inc \ 347 nm formation of triphenyl methyl (trityl) radicals and trityl ions. The quantum yields in dichloromethane solution are and Trityl '(Ph ions are assumed to be for
T h e photo-cleavage of S-S bond of 5,5'-dithiobis ( I-phenyl-1 H-tetrazole) has been studied by the nanosecond-laser flash photolysis method. The transient absorption band at ca 430 nm was attributed to I-phenyl-IH-tetrazole-5-thio radical forming by the S-S bond hssion For the reaction with conjug
