Abstract
The UV-visible and infrared spectra of $CF_{3}NO$ have been obtained on sodium chloride films at 77 and 89 K. From band shifts in the mid-IR, we have determined the mode of adsorption to be one in which the C-N axis is normal to the (100) face exposed at the surface, with the fluorines atop a sodium ion. The spectroscopically obtained isotherms were used in the calculation of the low-coverage limit to the heat of adsorption $(q_{0} = -18+2 kJ mol^{-1})$. At high coverages, multilayer adsorption was noted: spectral features attributed to the glassy liquid' phase observed by Gordon and coworkers1 were seen in the visible and infrared.
