Notes:
The vibrational spectra of (CH32PH) and (CD3)2PH have been studied and assignments made. In the infrared, the region 4000-33 cm-1 was recorded for the gaseous and solid states whereas the Raman spectra from 3500-10 cm-1 in the gaseous, liquid, and solid states were observed. There is some evidence of weak hydrogen bonding based on the behavior of the phosphorus-hydrogen stretching and bending modes. There also appears to be considerable interaction between the metnyl rocking and phosphorus-carbon stretching modes. The a″ and a′ torsional modes appear to be accidentally degenerate at 182 and 142 cm-1 for the ‘light’ and ‘heavy’ compounds, respectively, which gives barriers of 2.14 and 2.30 kcal mole-1, respectively.
