Abstract
A new atlas of CH4 lines in the 1120–1800-cm−1 region has been generated, based on laboratory spectra taken with a Nicolet interferometer at 0.06-cm−1 resolution with 635-cm path length at pressures of 0.98 Torr, 4.86 Torr, and 19.97 Torr. A compilation of line positions and line intensities includes 1339 CH4 lines, several hundred of which have not been previously observed.Keywords
