Zusammenfassung:Title screen
Themain goal of the present study was to improve the already published rotational structure analysis of the ground vibrational state of the 13CH3Dmolecule. To realise that,we recorded high-resolution spectra of a set of the strongly interacting vibrational bands, 2ν3(A1), 2ν6(A1), 2ν6(E), ν2(A1), ν5 + ν6(A1), ν5 + ν6(A2), ν5 + ν6(E) and ν3 + ν6(E). From the analysis ofthe experimental data, more than 1900 ground state combination differences (GSCD) were determined with J max = 18, _Jmax = 2 and Kmax = 15. The a1/a2 splittings of the states with quantum number K = 3 were taken into account. The presence of numerous forbidden transitions allowed us to determine with high accuracy GSCD not only with _K = 0, but with _K = ±1, ±2 and ±3, as well. Spectroscopic parameters of the ground vibrational state were determined from the joint fit of the obtained GSCD (they are reproduced with drms = 0.00014 cm−1). The 21 highly accurate THz-region transitions which were also used as input data, are reproduced with drms = 47 kHz.
