“…[33][34][35][36] We failed to observe any luminescence from the CN radicals when pumped with resonant light from the OPO around 400 nm corresponding to the 0←0 transition of the B 2 ⌺←X 2 ⌺ electronic transition 37,38 in agreement with the results of Bondybey et al 39 indicating that the nonradiative relaxation channels dominate in solid xenon.…”

The synthesis of novel rare-gas compounds HXeCN, HXeNC, and HKrCN is reported. HKrCN represents the first stable compound with a Kr-C bond. The novel molecules are formed in solid Xe and Kr by first photolyzing monomeric HCN with a 193 nm ArF laser at 7.5 K. The photolysis produces isolated hydrogen atoms and CN radicals as evidenced by IR spectroscopy and laser induced fluorescence. Annealing of the Kr matrix at ϳ30 K and Xe matrix at ϳ50 K activates the hydrogen atoms, and they react with rare-gas atoms surrounding the CN radicals producing the rare-gas compounds, which are characterized in this work by means of IR spectroscopy and ab initio calculations. Other products observed are HNC and H 2 CN. Infrared induced photochemical conversion of HXeNC to HXeCN is accomplished by exciting the Xe-H and C-N stretching fundamentals of HXeNC. The existence of low barrier between these two distinct isomers is confirmed by the ab initio calculations.

This review provides comprehensive coverage of the application of X-ray absorption spectroscopy (XAS, XAFS, EXAFS, XANES) to matrix isolated species. As X-ray absorption spectroscopy provides structural data without the need for long range order it has been applied to a large number of systems to yield unique structural data about both the matrix isolated species, and their interactions with the matrix host. To put the work into perspective there is a tutorial introduction to the theoretical background of X-ray absorption spectroscopy, data content, processing and analysis. In addition there is brief coverage of the use of other synchrotron radiation techniques for the study of matrix isolated species, and a consideration of future perspectives.

“…Valence to ionic state transitions shift to the red by several tenths to an electronvolt, due to the solvation of the ionic state through induction forces which scale with the polarizability of the matrix. Numerous studies have documented this effect. ,,− Semiquantitative treatments, such as the Onsager cavity model, while useful, remain limited by ambiguities, such as the definition of cavity radius. More rigorous treatments rely on self-consistent expansions of electrostatic interactions, including induced multipoles, and are relatively successful where implemented. ,, …”
