The room-temperature lifetimes of ring-substituted excited diphenylmethyl radicals have been shown to correlate well with the energy gap between the fluorescent lowest excited doublet and the ground state. Attempts to correlate the lifetimes with Hammett constants were unsuccessful.
The visible absorption spectra of all the monomethylbenzyl and monofluorobenzyl rachcals in the gas phase have been studied by laser-induced fluorescence. The fluorescence lifetimes of the stronger vibronic transltions have been measured. It is concluded that, unlike benzyl itself, a single excited
The pyrolysis of ethylbenzene has been investigated in shock waves with the laser schlieren technique. Mixtures of 1 and 2% ethylbenzene in krypton were studied for reaction conditions of 1300-1800 K, 70-550 torr. At high temperatures, the initial rapid endothermic dissociation is followed by a regi
