Vibrational distributions of HgBr(B2Σ) and HgI(B 2Σ) molecules formed by photodissociation of HgBr2 and HgI2

Article abstract of DOI:10.1063/1.441722

Reliable fluorescence spectra (+/- 3percent) of HgBr and HgI photofragments formed in the direct photodissociation of HgBr2 and HgI2 at 193 nm have been measured.The nascent vibrational distributions of HgBr(B²Σ) and HgI(B²Σ) have been determined.The distributions are revomable into the relative contributions from two process: (1) hν + HgX2 -> HgX(B²Σ) + X(²P_3/2) and (2) hν + HgX2 -> HgX(B²Σ) + X(²P_1/2).HgX(B²Σ) molecules formed with X(²P_3/2) atoms exhibit vibrational population inversion and preferential energy disposal among the higher vibrational states.In contrast, the vibrational excitation of HgX(B²Σ) molecules formed with X(²P_1/2) atoms produces a Boltzmann-like distribution which strongly favors the lowest vibrational states.
