| Popis: | This paper deals mainly with the modifications of molecular spectra when the density varies as a function of pressure and temperature. It represents a brief survey of some of the work conducted at Bellevue. The main topics covered are: (i) depolarized scattering of light by rare gases, due to anisotropic field fluctuations and atomic distortion; (ii) translational spectra in the far-infrared in dense rare gas media, and phonon bands, in solid rare gases; (iii) pressure induced spectra in the vibration–rotation region, in particular for hydrogen in solid argon, exhibiting localized and non-localized phonon bands; (iv) vibration–rotation spectrum of solid hydrogen up to 11 kbar pressure, revealing in particular the nature of the bands by the magnitude of their shifts; and (v) vacuum ultraviolet electronic spectra of some molecules trapped in rare gas matrices, or as pure solids; resonance line of pure solid Ne exhibiting very weak perturbation; deperturbation of NO valence transitions in a matrix, as observed under high resolution and with an improved model of the vacuum spark as a source. |
