“…The ClNO Raman frequencies in cyclohexane are reduced by 10-20 cm-' relative to the gas phase consistent with significant modification of the ground state potential energy surface in solution. Barham et al also reported resonance Raman depolarization ratios measured at wavelengths resonant with the A band, and these ratios were found to be less than one third consistent, with more than one excited state contributing to the observed scattering (157). This study was followed by a RRIA study of ClNO dissolved in both cyclohexane and acetonitrile (158).…”

“…The solution-phase photochemistry of ClNO has been recently investigated (157,158). The absorption spectrum of ClNO in cyclohexane is similar to that of gaseous ClNO; however, the breadth of the A band increases and the maximum of this band redshifts by 10 nm relative to the gas phase ()Llllai( = 206 nm) (157). The integrated intensity of the A band is the same for both the gaseous ClNO and ClNO in cyclohexane indicating that groundexcited state energetics or the excited-state displacements (or both) are environment dependent.…”

Recent progress in understanding the phase-dependent reactivity of halooxides and nitrosyl halides is outlined. Halooxide reactivity is represented by the photochemistry of chlorine dioxide (OClO) and dichlorine monoxide (ClOCl). The gas phase photochemical dynamics of OClO are contrasted with the dynamics in condensed environments. The role of excited-state symmetry in defining the reaction dynamics and the observation of photoisomerization resulting in the production of ClOO are discussed. The current understanding of the excited-state reaction dynamics of ClOCl and evidence for photoisomerization of this species resulting in the production of ClClO are outlined. Finally, the photochemical reaction dynamics of the nitrosyl halide ClNO are presented. The main difference between the gas and condensed phase reaction dynamics of this species is that whereas photodissociation to form Cl and NO dominates the gas phase reaction dynamics, photoisomerization resulting in ClON production occurs to an appreciable extent in condensed environments. The observation of photoisomerization for OClO, ClOCl and ClNO suggests that this process is a general feature of the condensed phase reaction dynamics for smaller halooxides and nitrosyl halides. Finally, future areas for study in both halooxide and nitrosyl halide photoreactivity are outlined.
