TL;DR: In this paper, the authors used the scanning imaging absorption spectrometer for atmospheric chartography (SCIAMACHY) pre-flight model satellite spectrometers to measure the gas-phase absorption spectra of the most important atmospheric trace gases (O3, NO2, SO2, O2, H2O, CO, CO2, CH4, and N2O) in the 230-2380 nm range at medium spectral resolution and at several temperatures between 203 and 293

TL;DR: In this article, high-resolution absorption cross-sections of glyoxal have been recorded at 296 k in the ultraviolet and visible (UV-vis: 19000-40000 cm−1, 250-526 k) spectral ranges by means of a Fourier transform spectrometer (FTS).

TL;DR: In this article, a multispectrum nonlinear constrained least squares approach based on Optimal Estimation was applied to derive the spectroscopic parameters by simultaneously fitting laboratory spectra at different ambient pressures assuming a Voigt line-shape.

TL;DR: In this paper, multivariate statistical separation techniques were used to obtain the spectrum of ground state I2+O3 formed in photolysis of I2 + O3, and the uncertainty due to uncorrected foreign absorptions is of no more than ± 3%.

TL;DR: In this article, the absorption spectra of gas-phase OClO in the 325-435 nm region (23,000-31,000 cm−1) were measured at five atmospheric temperatures between 213 and 293 K with a spectral resolution of 1.0-1.
