Description

The microwave spectra of 15N isotopic species of nitrosyl chloride, "NO"Cl and "NO"Cl, have been assigned between 8 and 26 GHz, and the following rotational constants have been obtained: A=81600 MHz, B=5693.80 MHz, and C=5322.44 MHz for "NO35Cl A=81520 MHz, B=5556.07 MHz, and C=5201.56 MHz for '5NO37Cl The microwave spectra of the normal species of nitrosyl chloride as well as the "Cl species and the "O species have already been measured by Millen et al. (1961). An analysis of both the rotational constants obtained in this study and the constants by Millen et al. has given the following bond lengths and anagle as the complete r3 structural parameters of nitrosyl chloride. r(N-0)=1.14370.006A, r(N-Cl)=1.9730.003, k, and LONCl=113.2°0.5° The nuclear quadrupole coupling constants in the N-Cl bond axis system of "NO"Cl are Xzz=7.8 MHz and 77=.311.
