Title: Absorption Spectra of Solid Methane, Ammonia, and Ice in the Vacuum Ultraviolet 

Journal/Source: J. Chem. Phys., 33, 270-274, (1960); doi:10.1063/1.1731096


Data: (diagram, table, disk): diagram

Energy/Wavelength range: < 170 nm

Resolution: 

Temperature: < 273 K

Temperature dependence: no

Pressure/Concentration: 

Phase (gas, liquid, solid): solid

Comments: The vacuum ultraviolet spectra of solid ammonia and ice are found to be shifted to higher frequencies relative to the 
corresponding vapor spectra by 7000 cm-1.
In methane, which forms a pure van der Waals solid, the spectra of gas and solid are found to be very similar.
