Nitromethane, with its heavy frame and internal rotator, readily evaporates into the atmosphere making it an ideal candidate for remote sensing. Here we present the absorption spectra of gas-phase nitromethane between 9 and 50Â cmâ1. Measurements were taken using a Bruker IFS 66v Fourier transform far-infrared (FTIR) spectrometer at a resolution of 0.12Â cmâ1 (0.0036Â THz) from 9 to 40Â cmâ1 and a Bruker Vertex 80v FTIR spectrometer with a resolution of 0.0075Â cmâ1 (0.00226Â THz) from 10 to 50Â cmâ1. The absorption spectra were measured at multiple pathlengths ranging from 2 to 6Â m. These measurements were used to calculate the absorption coefficient of nitromethane as a function of wavenumber.
