✦ Synopsis

The n 2 /n 4 diad of phosphine has been investigated between 920 and 1080 cm 01 by laser sideband spectroscopy. Using 62 observed lines and more than 250 transitions measured by other authors, including microwave, far infrared, and laser Stark observations, a fit was performed, which achieved a standard deviation of 1.2 MHz. A 1 /A 2 splitting due to vibrational rotational interaction could be resolved in ten transitions.

The high-resolution (0.005 cm -1 ) Fourier transform infrared spectrum of PH 3 is recorded and analyzed in the region of the fundamental stretching bands, ν 1 and ν 3 . The ν 2 + ν 4 and 2ν 4 bands are taken into account also. Experimental transitions are assigned to the ν 1 , ν 3 , ν 2 + ν 4 , and

To complete the analysis of the complex infrared spectra of 14 NH 3 in the 4-to 8-µm region, we assigned nearly 1200 transitions in the 3ν 2 -ν 2 , ν 2 + ν 4 -ν 2 , ν 1 -ν 2 , ν 3 -ν 2 , 2ν 4 -ν 2 , and 4ν 2 -ν 2 hot bands using the upper state energy levels determined by our previous studies at 4 a
