Infrared Absorption Spectra of H2SO4, SO3, SO2, and H2O at 300C and 350C

Mid infrared absorption spectra of sulfuric acid (H2SO4), sulfur trioxide (SO3), sulfur dioxide (SO2), and water (H2O) were collected in a high temperature gas cell operating at either 300C or 350C. The spectra were collected using tunable external cavity quantum cascade lasers (ECQCLs) tuning, which were capable of operating over the wavelength range from approximately 7 microns to 9 microns, where H2SO4 and SO3 have their strongest absorption features. The spectra can be used as a library for developing gas sensors.

本数据集采集了硫酸（H₂SO₄）、三氧化硫（SO₃）、二氧化硫（SO₂）与水（H₂O）的中红外吸收光谱。所有光谱均在工作温度为300℃或350℃的高温气体池中采集，采集设备为可调谐外腔量子级联激光器（ECQCLs）；该激光器可覆盖约7微米至9微米的波长范围，而硫酸与三氧化硫的最强吸收特征正处于此区间。本光谱数据集可作为气体传感器开发的参考谱库。
