✦ Synopsis

Infrared

bands due to vj + v4, vz, vj and v4 were recorded for the species CH,CN, "CH,CN, CH,"CN and CHsC'sN in the solvents carbon tetrachloride, chloroform, benzene, pyridine and dimethyl sulphoxide.

Values of W,,., were extracted by the modified Winther method, which are slightly less, 11.2-l 1.9 cm-', than the value in the gas, 12.15 cm-'. Relative intensity measurements of 11) + r4 and v2 in Ccl, are compatible with an unperturbed intensity ratio, I ,,, +,.,/I v2 of -0.03. The fallibility of the infrared intensity method for determining W, and the need for precise frequency data in the Winther method, are stressed.

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
