Rotational analysis of the ν1, ν4, ν5 and 2ν6 infrared bands of CF3CN
Abstract
The rotational structure in the parallel bands ν1, ν4 and 2ν6 and in the perpendicular band ν5 of CF3CN is fully analysed at a resolution of 0.06 cm–1. The main features of these four bands have been qualitatively explained and 320 lines have been assigned. The band centres have been found at 2277.552, 521.147, 1249.361 and 1214.395 cm–1, respectively. The rotational and centrifugal distortion constants in the ground state and first excited level along with the Coriolis constant have also been calculated.
