Pressure broadening in Raman spectra of CH4–N2, CH4–CO2, and CH4–C2H6 gas mixtures
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2023Different molecular environments change the spectrum of a given gas sample involved in a mixture compared to the spectrum of a pure gas. It is necessary to account for this effect to improve the accuracy of the analysis of the natural gas composition by Raman spectroscopy.

Accurate rovibrational spectroscopy of relevant astrochemical complexes: CH4⋯CH4, CH4⋯N2 and CH4⋯Ar
Spectrochimica Acta Part A: Molecular and Biomolecular SpectroscopyRovibrational spectroscopic properties of CH4⋯CH4, CH4⋯N2, and CH4⋯Ar weakly bound complexes are relevant to astrophysics and astrochemistry, with particular interest to research on Titan's atmosphere. Different methodologies were applied to achieve the high accuracy required to fill the data gap in the literature of these complexes, particularly ...

Rotational tunneling in CH4 under pressure (CH4 III)
The Journal of Chemical Physics, 1982High resolution neutron inelastic scattering techniques were used to measure tunneling spectra of methane (CH4) in its phase III. By increasing the pressure from 0.6 to 1.8 kbar the tunneling lines shift by about a factor of 1.5. The rather complicated spectra can be equally well described by two simple structural models.

Dynamics of CH4 oxidation in landfill biocover soil: Effect of O2/CH4 ratio on CH4 metabolism
Environmental Pollution, 2012The CH(4) oxidation dynamics was investigated by observing the CH(4) oxidation rates at concentrations (from 1.0 × 10(4) ppmv to 2.0 × 10(5) ppmv) mixed with O(2) (from 5.0 × 10(4) ppmv to 7.5 × 10(5) ppmv). The CH(4)-O(2) dual-substrate model based on Michaelis-Menten equation (K(m, CH4) = 1.4 × 10(5) ppmv; V(max) = 7.6 × 10(2) μmol kg(-1) d(-1); K(m,
