Abstract
We report results of spectroscopic measurements with a continuous-wave distributed-feedback quantum-cascade laser (DFB QCL). Line intensities and self-broadening coefficients were measured in the ν<sub>1</sub> band of SO<sub>2</sub> between 1088 and 1090 cm<sup>-1</sup>. The self-broadening coefficients in this paper confirm the typical decrease of ν<sub>self</sub> with increasing rotational quantum number <i>K</i>’’<sub>a</sub>. The line intensities determined here are smaller than those in the HITRAN 2000 database. Several lines found in this study were not present in the database.
