Název v původním jazyce

Rotational and Rovibrational Spectroscopy of CH3NC of the Ground and v(4)=1 Vibrational States

Popis výsledku v původním jazyce

The parallel vibration-rotation band v(4) of methyl isocyanide (CH3NC), with a band center at 944.9 cm(-1), was studied by FTIR spectroscopy between 890 and 980 cm(-1) in order to improve the ground-state rotational constants. Such improvement is essential for the scheduled studies of excited vibrational levels and their mutual anharmonic resonances occurring at higher values of the K rotational number. Ground-state combination differences generated from this band, spanning values of J/K from 0 to 85/13, were combined with rotational data from the literature and newly measured rotational transitions, extending the J/K range from 3/0 up to 31/14, and fitted simultaneously with a fully quantitative reproduction of the data. The infrared data of the v(4)band were analyzed together with rotational data of the v(4) = 1 level, spanning values of J/K from 4/0 to 14/12.
