Compounds Containing the Carbonyl Group
TL;DR: In this paper, the authors discuss the factors that shift carbonyl bands in the infrared and Raman spectra and show that the C=O stretching frequency is relatively insensitive to a change in the mass of an atom directly attached to the C = O carbon as long as that atom is carbon or a heavier atom.

Calculation of Energy Levels for Internal Torsion and Over-All Rotation. III
TL;DR: In this paper, a general treatment of hindered internal rotation is given for molecules that can be regarded as a rigid symmetric top attached to a rigid frame which may be completely asymmetric.

Infrared, Raman and near-ultraviolet spectra of CF3COZ compounds—II. Hexafluoroacetone☆
TL;DR: In this article, the infrared spectrum of hexafluoroacetyl chloride and the Raman spectrum of the liquid have been studied and a complete vibrational assignment suggested, showing that the symmetry of the molecule is Cs, which implies that the two CF3 groups are staggered with respect to each other, presumably due to steric interaction.

The infrared spectrum of SiF4
Julian Heicklen,Vester Knight +1 more
TL;DR: In this paper, the infrared spectra of normal (Si 28 ) and isotopically enriched (Si 29 and Si 30 ) SiF 4 were observed from 300 to 2100 cm −1 on a grating instrument operating in a vacuum.

Infrared, Raman and near-ultraviolet spectra of CF3COZ compounds—I Trifluoroacetyl chloride
TL;DR: The Raman spectrum of liquid CF 3 COCl and the infrared spectra of the gas and the condensed solid have been studied, and fundamental frequencies assigned as discussed by the authors, and it was shown that the barrier to internal rotation in CF3 COCl is 400-500 cm −1, which would put the torsional vibration at 37-43 cm − 1, thus either the barrier is surprisingly low or the band is so weak that it has escaped detection.

Vibrational spectrum and barrier to internal rotation for CF3CFO
Karl R. Loos,R.C. Lord +1 more
TL;DR: In this article, the vibrational spectrum of CF3CFO has been investigated over the range 3900-35 cm−1 with small grating spectrometers and the principal moments of inertia of the molecule have been estimated from assumed bond angles and distances to be 130, 206, and 248 a.m.u.
