| Abstract: | The rotational constants and quartic centrifugal distortion constants for NO235Cl and NO237Cl have been determined from an analysis of rotational transitions in the microwave and millimeter wave regions between 8.2–40 and 90–120 GHz, respectively.The values of the in-plane force constants in the general harmonic potential field have been obtained by combination of infrared and microwave data. Vibrational frequencies of 14NO2Cl and 15NO2Cl, inertia defects of NO235Cl in the excited vibrational states v3 = 1 and v5 = 1, and first-order centrifugal distortion constants of NO237Cl are the experimental data used in the least-squares fitting determination of force constants. |
