Infrared spectrum of hydrobromic aid
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1960 A precise measurement of the infrared fundamental bands of HBr79 and HBr81 has been made. The two band centers have been found to be 2,558.94 and 2,558.56 cm-1, respectively. Rotational and vibrational constants have been calculated from the observed data. The constants are in good agreement with previous reported values.

Infrared Spectrum of Acetylene*
Journal of the Optical Society of America, 1956 The infrared absorption spectrum of C2H2 has been studied in the region from 2500 to 4150 cm−1. Nineteen bands were observed, of which 11 were sufficiently intense and well resolved to permit rotational analysis. Five bands involving the ground vibrational state were analyzed giving the rotational constants B0=1.17654±0.00004 and D0=1.51±0.03×10−6 cm−1.

The infrared spectrum of the benzene–Ar cation [PDF]
The Journal of Chemical Physics, 1999 The infrared (IR) absorption spectra of the jet-cooled C6H6 and C6D6 cations, complexed with Ar, are measured throughout the 450–1500 cm−1 region via IR-laser-induced vibrational dissociation spectroscopy. The IR spectrum of the C6H6–Ar cation is dominated by a Fermi resonance between the IR active ν11 mode and two components of the combination mode of

THE HIGH-RESOLUTION INFRARED SPECTRUM OF HCl+ [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT The chloroniumyl cation, HCl+, has been recently identified in space from Herschel's spectra. A joint analysis of extensive vis-UV spectroscopy emission data together with a few high-resolution and high-accuracy millimeter-wave data provided the necessary rest frequencies to support the astronomical identification. Nevertheless,

The infrared spectrum of the He–C2D2 complex
The Journal of Chemical Physics, 2015 Spectra of the helium-acetylene complex are elusive because this weakly bound system lies close to the free rotor limit. Previously, limited assignments of He–C2D2 transitions in the R(0) region of the ν3 fundamental band (≈2440 cm−1) were published.

Dichroism of the Infrared Spectrum of Nerve
Biophysical Journal, 1973 Infrared spectra were obtained from the sciatic and optic nerves of the frog (Rana sp.) and the trigeminal and olfactory nerves of the garfish (Lepisosteus osseus). The myelinated nerves showed dichroism at several absorption peaks, particularly 1,220-1,230 cm(-1), but the nonmyelinated nerves showed little or no dichroism.

Infrared predissociation spectrum of HeNe+
Chemical Physics, 1985 Abstract One hundred and seven transitions of the HeNe + ion have been observed using the technique of infrared predissociation spectroscopy. Seventy-eight of the lines have been assigned to rotational components of the A 2 2 Π 1 2 -X 2 Σ + system.

Infrared spectrum of chlorofluoromethane
Journal of Research of the National Bureau of Standards, 1950 In order to compare its spectrum with that of other halogenated methanes, the infrared spectrum of chlorofluoromethane has been measured in the gaseous state from 2 to 30 microns. The longest wavelength band was observed at 26 microns. Twenty-five bands have been observed with cells of 5, 60, and 100 centimeters in length and with gas pressures up to ...

Infrared spectrum of FeF2 [PDF]
Journal de Physique Lettres, 1979 Infrared reflectivity spectra at room temperature are presented for the rutile structure compound FeF2 and analysed by two methods : a classical oscillator response and a Kramers-Kronig analysis. A weak supplementary sideband appears in the spectrum for polarization parallel to the axis. An interpretation by a twophonon process is proposed.
