Test of Velikovsky theory for dense hydrocarbon clouds and dusts surrounding Venus, using IR reflection spectra
Gas chromatographic and mass spectrometric analyses of alicyclic hydrocarbons from Carboniferous organic materials, noting alkane distribution and evolutionary histories
High temperature equilibria from hydrocarbon plasma sources subjected to 3000 W RF electrodeless discharge
Aromatic and nonaromatic hydrocarbon fractions in terrestrial graphite, discussing classification and analysis by chromatography and mass spectrometry
Absorption coefficient measurement for hydrocarbon gases for He-Ne laser beam at 3.39 microns, tabulating coefficients, noting variations from spectroscopic data
Portable instrument passes light from helium-neon laser at a wavelength of 3.39 microns through the atmosphere being monitored and measures attenuation of the laser beam. Since beam attenuation is due almost exclusively to absorption of radiation by hydrocarbons, a quantitative measure of their concentration is available.
