โฆ Synopsis
Single-photon dissociation of Hg(CH& at 248 and 193 nm produces CH, radicals with substanual ewxauon in Ihe ~2 out4planc bend and the uj antisymmetric stretch. At 218 nm the antisymmetnc stretch excdation is charackrized by a 1200-1500 K rotational temperature and a nbratiorul dlslrlbuuon sl : ~2 : ~3 of I 0 : 0.ZrO.l : O.OS*O.OS.

The mechanism for production of ekctronically excited photofragments from the title molecules is investigated using two excimer lasers in a pump-probe experiment. We find for NH(A) from NH3. N2H4 and CH3NH2; OH(A) from HN03 and CN(B) and CH(A. B) from CH;NH, that secondary excitation of primary phot
