【 摘 要 】

Line strengths and line shape parameters have been measured for a single absorption transition of both hydrogen chloride and hydrogen fluoride gases. These parameters were determined from spectral absorbance measurements over a range of temperatures and pressures using single-mode laser diodes as the laser sources. The measured parameters are compared to values reported in scientific literature. Significant differences are observed that will impact spectroscopic measurements of species concentrations, temperature, and pressure.
