摘要: The millimeter rotational spectrum of NO2F has been measured in the frequency range 90–200 kMc/sec. By centrifugal distortion analysis, based on Kivelson and Wilson first‐order perturbation treatment, following values ground‐state parameters were obtained: A = 13 201.31 B = 11 446.25 C = 6118.99 τaaaa = − 0.039814 τbbbb = − 0.078638 τaabb = 0.012452 τabab = −0.048868. Two different methods used order to determine general quadratic force field, by combination infrared microwave data. first method is complete consistency between constants vibration frequencies normal species best fit spectrum. second uses least‐square determination corrections some starting set constants. All isotopic‐ normal‐species Bernitt, Miller, Hisatsune all contributions millimetric transitions as experime...
