Popis: The Raman active fundamentals ν1(A1g), ν2(Eg), ν5(F2g), and the overtone 2ν6 of SF6 have been investigated with a higher resolution and the band origins were estimated to be: ν1 = 774.53 cm−1, ν2 = 643.35 cm−1, ν5 = 523.5 cm−1, and 2ν6 = 693.8 cm−1. Raman and infrared data have been combined for estimation of several anharmonicity constants. The ν6 fundamental frequency is calculated as 347.0 cm−1. From the analysis of the ν2 Raman band, the following rotational constants of both the ground and upper states have been calculated: B 0 = 0.09111 ± 0.00005 cm −1 ; D 0 = (0.16±0.08)10 −7 cm −1 ; B 2 = 0.09116 ± 0.00005 cm −1 ; D 2 = (0.18±0.04)10 −7 cm −1 .
