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...

Water vapor absorption of visible and near infrared radiation.

Water vapor error function absorption coefficients for visible and near ir radiation have been recalculated from experimental transmission data. The error function absorption coefficients and the resulting transmissions as a function of precipitable water vapor are tabulated for wavelengths from 0.2 micro to 1.3 micro. Comparisons are made between computed and measured spectral transmittances.

Infrared and Millimeter-wavelength Absorption by Atmospheric Water Vapor

The propagation of electromagnetic radiation is affected by three major phenomena: absorption, scattering, and turbulence. Absorption by molecular water vapor is the dominant mechanism of tropospheric attenuation at millimeter and infrared wavelengths, especially in the marine environment. Therefore, the understanding and accurate modeling of absorption by this molecule are important to atmosph...

Infrared water vapor continuum absorption at atmospheric temperatures.

We have used a continuous-wave carbon dioxide laser in a single-mode realization of cavity ring-down spectroscopy to measure absorption coefficients of water vapor at 944 cm(-1) for several temperatures in the range 270-315 K. The conventional description of water vapor infrared absorption is applied, in which the absorption is modeled in two parts consisting of local line absorption and the re...

Infrared 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...
