Rovibrational spectroscopy of the Fermi-interacting v4 = 1 and v3 = v 6= 1 levels of DCF3

Popis výsledku v původním jazyce

The high-resolution infrared spectrum of deuterated fluoroform (DCF3) was studied in the 700 and 1200 cm-1 regions, with the aim to assign and analyze the 4 CF3 asymmetric stretching vibration. The Fermi-type anharmonic coupling between the v4 = 1 and v3= v6 = 1 rovibrational levels, already mentioned in an early work of Ruoff et al. [Spectrochimica Acta A 31 (1975) 1099-1100], was studied for the first time with high resolution in the current work. Assignments in the 3+6/4 band system were confirmed and extended by the identification of the 3+6-6 and 4-6 bands in the 700 cm-1 region, the latter being enhanced near the Fermi crossings of the studied levels. Data from both the hot and difference bands were included in the analysis. The close separationof the studied vibrational levels of about 14.8 cm-1 produces a large variety of resonance crossings which involve levels with . Besides the Fermi ( ) and Coriolis ( ) resonances, they were accounted for by inclusion of additional higher
