Abstract

A large set of laboratory transmission spectra of water vapor within the v₂ band has been collected and analyzed in order to better understand its pressure broadening characteristics. Topics considered in this study include an examination of the low J ${\text{H}}_2^{16}\text{O}$ N₂-broadened Lorentz line-widths, determination of the self- and N₂-broadened continuum coefficients, and an examination of the near- to intermediate-wing lineshape of N₂-broadened water vapor. The spectra were collected using a BOMEM FTS and a White-type multi-pass absorption cell. Details concerning the experimental set-up and data collection process can be found elsewhere [1].
