Analysis of the microwave spectrum of hydrogen selenide

摘要: Exact expressions of the rotational energy including centrifugal distortion effect were obtained for low JK states and applied to analysis microwave spectra hydrogen selenide molecules observed by Jache et al. The molecular structure in ground vibrational state was method suggested previously authors. results are as follows: rz(SeH) = 1.4754 ± 0.0007 A , 1.4711 0.0003 < (HSeH)z 90°51.5′ 3′ , (DSeD)z 90°52.6′ 1′ . The difference between rz(SeH) rz(SeD) well interpreted terms anharmonicity vibration. A trial done determine equilibrium constants stretching vibration from rz structures H2Se D2Se. result is 1.4605 0.003 A < (HSeH)e 90°55′ 5′ F3(SeH) (4.55 0.8) × 1013dyne cm−2 .
