摘要: Abstract The rotational structure of four a-type bands, ν2, ν3, 2ν2 and 3ν2, gaseous formaldehyde were analyzed as asymmetric-rotor bands by using computed band contours. constants obtained from the microwave spectrum in ν2 vibrational state confirmed infrared spectra. In ν3 effect c-type b-type Coriolis interactions with ν6 ν4, respectively, was detected unperturbed values obtained. Band origins 2ν2, 3ν2 gave an anharmonicity constant x22 = 10.2 ± 0.2 cm−1.
