| Abstract: | The determination of rotational Raman spectra for hydrogen gas at 354.9, 587.4, 814.7 and 1035.1 cm(-1) by FT-Raman spectrometry is described in this paper. The Raman bands at 354.9 and 814.7 cm(-1) were assigned to rotational levels J = 0 --> J = 2 and J = 2 --> J = 4 for parahydrogen, and those at 587.4 and 1035.1 cm(-1) were assigned to rotational levels J = 1 --> J = 3 and J = 3 --> J = 5 for orthohydrogen. The interatomic distances determined for orthohydrogen and parahydrogen molecules with nonrigid rotator model are 75.03 and 74.98 pm, respectively. |
