    Measurement of integrated intensities of acetylene bands at 3.04, 7.53 and 13.7 microns (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Integrated intensities of acetylene bands at 3.04, 7.53, and 13.7 microns measured at 300 K at a spectral resolution of 0.6 slit widths per cm, using the technique described by Penner (1959), are presented. Comparisons with other published measurements suggest that the presented intensity values are reasonably well determined.

    Measurement of line intensities of linear molecules under low resolution (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Spectral absorption measurements involving pure nitrous oxide were performed with the aid of a commercial grating spectrophotometer. A multiple reflection cell with a path length of 1.25 m was used in the investigation. The tests were conducted at pressures in the range from 5 to 8 atm. The obtained data were used to determine the apparent spectral absorption coefficients. Questions regarding the validity of a line approximation relation are discussed.

    The nu sub 9 fundamental of ethane - Integrated intensity and band absorption measurements with application to the atmospheres of the major planets (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Measurements of the absolute intensity and integrated band absorption have been performed for the nu sub 9 fundamental band of ethane. The intensity is found to be about 34 per sq cm per atm at STP, and this is significantly higher than previous estimates. It is shown that a Gaussian profile provides an empirical representation of the apparent spectral absorption coefficient. Employing this empirical profile, a simple expression is derived for the integrated band absorption, which is in excellent agreement with experimental values. The band model is then employed to investigate the possible role of ethane as a source of thermal infrared opacity within the atmospheres of Jupiter and Saturn, and to interpret qualitatively observed brightness temperatures for Saturn.

    Measurement of multiplet intensities and noble gas-broadened line widths in the nu 3 fundamental of methane (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Presented integrated intensity data at 300 K for J multiplets between P(11) and R(11) in the nu-3 fundamental of C-12 methane are shown to be in good agreement with most previously published pertinent values. Also, line widths measured at 100 K, 130 K, 190 K, 250 K, and 300 K for R(0), R(1), and R(2) broadened by He, Ne, and Ar are presented, and the line-width temperature dependence is discussed for the three cases of broadening.
