Abstract

We present an experimental study of the self- and N₂-broadened H₂O continuum in microwindows within the ν₂ fundamental centered at ~1600 cm⁻¹. The continuum is derived from transmission spectra recorded at room temperature with a BOMEM Fourier transform spectrometer at a resolution of ~0.040 cm⁻¹. Although we find general agreement with previous studies, our results suggest that there is significant near-wing super-Lorentzian behavior that produces a highly wave-number-dependent structure in the continuum as it is currently defined.
