Abstract
The infrared absorption of solid phosphine has been measured in the region of 4 °K to 68 °K. An hitherto unreported transition at about 10 °K has been observed. Above this temperature the spectrum is characteristic of a disordered system; below 10 °K the absorption arising from the symmetric vibrational modes exhibits a fine structure composed of sharp lines. The large number of lines attributed to v2 are interpreted as arising from inversion doubling, indicating a residual disorder in the system.Keywords
