Abstract
AbstractTo analyze the absolute line intensities, as well as the coefficients of air‐ and self‐broadening of water vapor, 31 transition lines were measured using an external‐cavity diode laser (ECDL) in the range of 9090–9750 cm−1. A multispectrum fitting (MSF) program was used in conjunction with a quadratic speed‐dependent Voigt profile (qSDVP) and a Voigt profile (VP) to extract the line intensities and self‐ and air‐broadening coefficients. Values at room temperature (296 K) were then compared with the HITRAN2016 and HITRAN2020 database. The analysis results show that the line intensities and air‐broadening coefficients are more consistent with the database while also verifying that the self‐broadening coefficients obtained based on qSDVP are larger than those based on VP.
