Abstract
We report argon-broadened water vapor transition parameters and their temperature dependence based on measured spectra spanning 6801-7188 cmâ1 from a broad-bandwidth, high-resolution dual frequency comb spectrometer. The 25 collected spectra of 2% water vapor in argon ranged from 296â¯K to 1305â¯K with total pressure spanning 100â¯Torr to 600â¯Torr. A multispectrum fitting routine was used in conjunction with a quadratic speed-dependent Voigt profile to extract broadening and shift parameters, and a power-law temperature-dependence exponent for both. The measurements represent the first broad bandwidth, argon-broadened water vapor absorption study, and are an important step toward a foreign-gas-perturbed, high-temperature database developed using advanced lineshape profiles.
