Abstract
The absorption spectrum of nitrosyl chloride has been studied in the region between 21,000 and 23,000 mc/sec. Eight groups of closely spaced absorption lines have been observed; thirty-one individual lines have been resolved. The main features of the observed spectrum can be satisfactorily explained in terms of the rotational transition J = 1→2 for molecules in the ground and lowest excited vibrational state; the observed hyperfine-structure is satisfactorily explained in terms of nuclear quadrupole interactions involving the chlorine nuclei. The rotational constants for molecules in the ground vibrational state are: for NO, , , and ; for NO, , , and . Values for the quadrupole interaction terms are given. The ratio obtained in this study was 1.34±0.08.
