High-resolution FTIR spectrum and analysis of the ν2+ν4 combination band of 32SF6

A preliminary prediction of the (ν2 + ν4) combination band of 34SF6

“…(8) To calculate transition intensities for infrared absorption, the dipole moment is expanded using the same methods, as descripted in [7].…”

Symmetry-adapted tensorial formalism to model rovibrational and rovibronic spectra of molecules pertaining to various point groups

“…Several infrared active fundamentals [61,64], Raman active fundamentals [60,62,63], harmonic [63,66], combination [45,62,83], and hot bands [61,63] have been analyzed recently. The reader can also refer to the review [67].…”

Analysis and modeling of combination bands of sulfur hexafluoride 32SF6 based on global fits. Update of the SHeCaSDa database

“…The ν 4 bending region in the infrared could be studied, along with the first hot band to be analyzed for this species, namely ν 4 + ν 6 − ν 6 [26]. Different combination and difference bands could also be analyzed [27,28,29,30]. The low-lying "forbidden" mode ν 6 , which is the origin of many hot bands, could be studied in detail for the first time, since it gains a very weak intensity through Coriolis couplings with other vibrational modes [31].…”
