✦ Synopsis

The Fourier transform infrared spectrum of monoisotopic 80 SeF 6 has been recorded in the 760-792 cm 01 region with an effective resolution of ca. 2.3 1 10 03 cm 01 . The 80 SeF 6 sample was prepared by burning monoisotopic 80 Se powder (99.2%) in an excess of fluorine. The analysis of infrared transitions of the n 3 band enabled the determination of parameters of the Hamiltonian developed up to the third order and the fourth order. The standard deviation obtained is equal to 4 1 10 04 cm 01 for the third-order development and 3.2 1 10 04 cm 01 for the fourth-order development. In the two analyses, 2900 lines were assigned and fitted.
