  The spectroscopy and intramolecular vibrational energy redistribution dynamics of HOCl in the vOH=6 region, probed by infrared-visible double resonance overtone excitation

  摘要：

  We use infrared-visible double resonance overtone excitation to promote HOCl molecules to single, well-characterized rotational levels of high OH stretching states just above the HOCl→HO+Cl dissociation threshold on the ground potential energy surface. Double resonance spectra are monitored by laser induced fluorescence detection of the OH dissociation products. We present here the results obtained in the 6ν1 region of HO35Cl where we have studied states with J ranging from 4 to 25, Ka from 0 to 5 and energy up to 300 cm−1 above the dissociation threshold. In the spectra for Ka=0–3 states, the zeroth-order (nOH,nθ,nOCl)=(6,0,0) level is split by mixing with a nearby dark state. Because the two states have very different A rotational constants, their separation increases with Ka, but the effects of the mixing remain observable in the spectrum up to Ka=3. Comparison with preliminary results from HO37Cl, together with analysis of the rotational constants, allows us to identify the perturbing state as (4,4,2). The lack of further strong perturbations compared to the average density of states allows us to infer that most of the matrix elements for couplings between the (6,0,0) bright state and other dark states are less than ∼0.1 cm−1. The average intramolecular vibrational energy redistribution (IVR) rate implied by these matrix elements (2.5×109 s) is two orders of magnitude longer than the predictions of statistical rate theory, indicating that IVR is likely to be the rate limiting step in the unimolecular dissociation process from (6,0,0). The present work provides the spectroscopic foundation for direct time-resolved studies of the unimolecular dissociation dynamics presented in a forthcoming paper.

  Second Harmonic Generation Studies of Ozone Depletion Reactions on Ice Surfaces under Stratospheric Conditions

  摘要：

  Hypochlorous acid, HOCl, an important species in the proposed heterogeneous mechanism for stratospheric ozone depletion, has been observed directly at submonolayer amounts on a single crystalline basal ice surface at 155-188 K, using the nonlinear optical method second harmonic generation. The ice is held in equilibrium with its vapor pressure. Second harmonic generation signals from 290 to 310 nm spectroscopically characterize the species and enable us to follow isothermal desorption kinetics in situ. HOCl desorbs as a single species with a Delta G*(des) = 48 +/- 4 kJ/mol, close to the cohesive energy of ice itself. The lifetime of HOCl on the clean ice surface at 185 K is estimated to be 4 s and the equilibrium surface coverage at 10(-11) Torr HOCl to be around 4 x 10(11) molecules/cm(2), corresponding to about 0.1% of a monolayer. However, these same measurements performed on ice predosed with varying amounts of HNO3 show that the HOCl lifetime is lengthened by coadsorbed HNO3, depending on the HNO3 surface density.

  observed at 235 nm. Measured O(3P2) images arising from ClONO2 dissociation at 226 nm suggest that oxygen atoms result from the spontaneous dissociation of metastable NO3. The quantum yield of O atoms arising from the spontaneous dissociation of NO3 varies from 0.09 at 262 to 0.38 at 235 nm based on the derived internal energy distributions of the NO3 fragments. We also describe a Monte-Carlo forward-convolution
