The rotation spectrum of methyl alcohol from 20 cm-1 to 80 cm-1
(Elsevier, 1963)
The rotational spectrum of methanol vapor has been measured from 20 cm-1 to 80 cm-1. The observations have been compared with the predictions of Burkhard and Dennison and for the most part good agreement is found. Some ...
Infrared target and background radiometric measurements--concepts units and techniques
(Elsevier, 1963-09)
This report discusses concepts units and techniques for making and describing measurements of radiation from targets and backgrounds.
Total radiances and equivalent widths of isolated lines with combined Doppler and collision broadened profiles
(Elsevier, 1968-08)
Analytical expressions for total radiances and equivalent widths of isolated spectral lines with combined Doppler and collision broadened profiles are presented for isothermal paths.
Some measurements of the infrared spectral radiances and emissivities of hydrogen fluoride in combustion gases at 1000[deg]C
(Elsevier, 1964)
Spectral radiances and emissivities were determined from moderate-resolution emission and absorption measurements in the exhaust gases of a small rocket motor. Data was obtained in the 2 to 3 [mu] region for ClF3-NH3 ...
Spin forbidden bands in Cr III hexamine
(Elsevier, 1965-09)
A large deuterium isotope effect has been found in the spin forbidden bands of the chromium III hexamine complex. The significance of this is discussed.
Vibration-rotation interactions in infrared active overtone levels of spherical top molecules; 2[nu]3 and 2[nu]4 of CH4, 2[nu]3 of CD4
(Elsevier, 1962)
The theory of the vibration-rotation lines of the first overtones of the infrared active fundamentals of tetrahedral molecules has been re-examined. Theory predicts an overtone spectrum consisting of five P, Q, and R ...
Total radiances and equivalent widths of Doppler lines for nonisothermal paths
(Elsevier, 1967)
An analytical method similar to that used by (1) on Lorentz lines was applied to the problem of the growth of an isolated Doppler line for the case of nonisothermal paths. The results, given in terms of the total radiance ...
The electronic absorption spectrum of crystallinechromyl chloride at 1.7[deg]K
(Elsevier, 1968-01)
The spectrum of chromyl chloride, CrO2Cl2 , in the region 6000 A-3800 A hasbeen obtained for the crystalline substance at temperatures down to 1.7[deg]K. Three absorption systems have been observed, together with the start ...
Polynomial approximations of exponential integrals
(Elsevier, 1968-10)
A method is described to calculate polynomial approximations for exponential integrals. Tables of coefficients are presented for exponential integrals of the second, third and fourth order, which allow their rapid evaluation ...
Band strength and line half-width of the 10[middle dot]4 [mu] CO2 band
(Elsevier, 1967)
Experimental absorption data using a 10[middle dot]4 [mu] CO2 laser have been re-analysed. The band intensity of the 10[middle dot]4 [mu] (1000-0001) CO2 band is 0[middle dot]0184 cm-1 (atm cm273[deg]K)-1+/-5% at 300[deg]K ...
