TL;DR: In this article, the infrared spectra from 300-880 cm−1 of 208 inorganic substances are reported, nearly all of which are salts containing polyatomic ions, and a list of characteristic frequencies is given for twenty ions.

TL;DR: In this article, gas-phase infrared spectra from approximately 80 to 500 cm −1 have been measured for seven compounds containing two or three methyl groups attached to the same atom Bands have been assigned to torsional and low-frequency bending modes.

TL;DR: In this paper, the central single bond tensor in conjugated molecules has been studied in the far infrared using the potential function 2V = 3Σn=1 Vn (1 - cos nα), and the quantity [V1 + 4V2 + 9V3] was evaluated for all eleven compounds.

TL;DR: In this paper, the infrared spectrum between 33 and 400 cm−1 has been examined in the vapor and liquid phases for the following 26 compounds: o-, m-, and p-F, Cl, Br, and CH3 benzaldehydes; pyridine-2-, -3-, and 4-aldeydes; acetophenone and its o-,m-, andp- F derivatives; furan-2-aldehyde; and several monofluorostyrenes and -nitrobenzenes.

TL;DR: In this paper, the transition between excited torsional levels (0 → 1, 1 → 2, 2 → 3,...) have been measured in the infrared for several compounds and the observed frequencies provide the best test of the potential function for hindered internal rotation which has yet been made.
