Infrared absorption spectrum of carbon disulfide.
The infrared absorption spectrum of carbon disulfide has been remeasured in the region from 2 to 24 I' with cells up to 5 mm in t hickness. Fifteen bands were observed , some however being of low intensity. The strongest band for the liquid occurs at 6.621' , and t he second harmonic of this band was observed at 2.22 1' , but t he first harm onic, which should be at about 3.33 1' , was not obse...
متن کاملInfrared absorption spectrum of the simplest Criegee intermediate CH2OO.
The Criegee intermediates are carbonyl oxides postulated to play key roles in the reactions of ozone with unsaturated hydrocarbons; these reactions constitute an important mechanism for the removal of unsaturated hydrocarbons and for the production of OH in the atmosphere. Here, we report the transient infrared (IR) absorption spectrum of the simplest Criegee intermediate CH2OO, produced from C...
متن کاملMatrix-Isolated Infrared Absorption Spectrum of CH2IOO Radical.
The peroxyiodomethyl radical, CH2IOO, was generated in cryogenic matrices using tandem supersonic nozzles. One hyperthermal nozzle decomposes diiodomethane (CH2I2) to generate intense beams of CH2I radicals, while the second nozzle continuously deposits O2/argon (Ar) on the matrix at 10 K. The CH2I and O2 in the Ar matrix react to produce the target peroxy radical (CH2IOO). The absorption spect...
متن کاملInfrared Absorption Spectrum of Brushite from First Principles
Brushite, CaHPO4·2H2O, is a crystalline hydrated acidic form of calcium phosphate that occurs in both physiological and pathological biomineralization processes. Additionally, it is biocompatible in humans. Several groups have investigated the experimental Fourier transform infrared vibrational spectrum of brushite. These investigations have led to a longstanding debate concerning the correct a...
متن کاملWater in the near-infrared spectrum of comet 8P/Tuttle
High-resolution spectra of comet 8P/Tuttle were obtained in the frequency range 3449.0– 3462.2 cm−1 on 2008 January 3 UT using CGS4 with echelle grating on United Kingdom Infrared Telescope. In addition to observing solar pumped fluorescent lines of H2O, the long integration time (152 min on target) enabled eight weaker H2O features to be assigned, most of which had not previously been identifi...
