  Vibrational population dynamics of the HgI photofragment in ethanol solution

  摘要：

  The vibrational population dynamics of HgI fragments in ethanol solution, resulting from the 320 nm photolysis of HgI2, are examined both experimentally and by a simulation. The experiments reveal an HgI population distribution which rapidly relaxes toward equilibrium. At the earliest times, the HgI exhibits vibrational coherent wave-packet motion that dephases with a time constant of ca. 1 ps. These data are used to gain insight into the character of the solvated potential energy curves. The population relaxation was adequately reproduced by master equations which were formulated to incorporate the HgI anharmonicity and a solvent frequency dependent friction. This treatment characterizes the spontaneous vibrational relaxation timescale for the n″=1→0 transition to be ca. 3 ps, and is used to identify the relaxation rate constants for all other HgI level pairs. The simulations estimate that the initial excess energy of HgI is centered at n″≂10 which corresponds to a total excess energy of ca. 1050 cm−1.

  Reliable fluorescence spectra (±3%) 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(B 2Σ) and HgI(B 2Σ) have been determined. The distributions are resolvable into the relative contributions from two processes: (1) hν+HgX2→HgX(B 2Σ) +X(2P3/2) and (2) hν+HgX2→HgX(B 2Σ)+X(2P1/2). HgX(B 2Σ) molecules formed with X(2P3/2) atoms exhibit vibrational population inversion and preferential energy disposal among the higher vibrational states. In contrast, the vibrational excitation of HgX(B 2Σ) molecules formed with X(2P1/2) atoms produces a Boltzmann-like distribution which strongly favors the lowest vibrational states.
