✦ Synopsis
Ultraviolet emission produced by photoexcitation ofN0 at 50-80 nm is observed using synchmtmn radiation as a light source.
The emission increases at an excitation wavelength corresponding to the ionization potential of the NO+ (a) state. The emission spectra at several excitation wavelengths are dispersed and identified to be mainly the NO(y) band. The dependence of emission intensity on gas pressure and delay time indicates that the emission is produced by a secondary reaction, which is attributed to the energy transfer from NO+ (a) to NO.

Exposure of a monolayer of Cs adsorbed on a Ru (0001) surface to NO leads at first to dissociative chemisorption and in a later stage to molecular adsorption. During this latter stage emission ofexoelectrons signals the possibility for non-adiabatic processes, while with a clean surface efficient qu
An oscillating time profile was observed in the visible emission of NO; produced by an infrared photosensitized reaction in NO2 + SF6. The origin of the modulation was found to be the periodical heating of NO2 due to the sound wave generated by the heat released from SF6 upon infrared multiphoton ex
