• Photofragment fluorescence polarization following photolysis of HgBr₂ at 193 nm

  When HgBr2 (2–45 mTorr) is photolyzed by the linearly polarized output of an ArF excimer laser (193 nm), the visible emission from the HgBr B 2Σ+ fragment is found to be linearly polarized. The degree of polarization is 11.9%±1.5%, in close agreement with the theoretical value of 14.3% predicted for a 1Σg+(1A1) →1B2(1Σu+) dissociative transition in HgBr2. The addition of inert gases depolarizes the HgBr* emission. A simple model, developed to calculate the average angle through which the angular momentum vector of the HgBr* fragment is tipped by each hard sphere collision, fits well the pressure dependence of the depolarization.
• State‐to‐state V–T transfer in HgBr(<i>B</i> ²Σ): A comparison with information theoretic predictions

  The collisional relaxation of the vibrational distribution of HgBr(B 2Σ) molecules following initial laser excitation of the v=52 vibrational level has been monitored with observations of the HgBr(B 2Σ–X 2Σ) fluorescence. Spectral simulation methods, developed in previous studies of the nascent vibrational distributions of HgBr(B 2Σ) photofragment molecules, were used for the determination of vibrational state populations. State populations were measured for various degrees of relaxation as the pressure of chaperone molecules, He, Ne, Ar, Xe, and N2, was progressively increased. An exponential temporal decay characterizes the V–T relaxation of vibrational energy for each buffer gas. A single parameter, the exponential decay time for global V–T relaxation, is all that is required for an information theoretic synthesis of the entire detailed matrix of state-to-state V–T energy transfer probabilities. The computed V–T relaxation of the vibrational distribution, based on the a priori information theoretic predictions is in good agreement with experimental observations.
• Vibrational distributions of HgBr(<i>B</i> ²Σ) and HgI(<i>B</i> ²Σ) molecules formed by photodissociation of HgBr₂and HgI₂

  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.
