CH3D ICE ABSORPTION COEFFICIENTS V1.0

Metadata Updated: August 23, 2025

This data set is the result of laboratory transmission spectroscopy experiments performed within a sealed cell in the ice laboratory at Northern Arizona University. We record spectra at wavelengths from 1 to 6 microns to study CH3D bands at 2.47, 2.87, and 4.56 microns (as indicated by '25', '29' and '45' in the data file names). We report temperature-dependent absorption coefficients of these bands when the CH3D is diluted in CH4 ice and also when it is dissolved in N2 ice. These absorption coefficient spectra can be combined with data from the literature to simulate arbitrary D/H ratio absorption coefficients for CH4 ice and for CH4 in N2 ice. The data were originally published in 2011 in Icarus, vol. 212, pp. 941-949, and that paper should be consulted for details about laboratory procedures and limitations of the data.
