From Molecules to Atmospheres.
How relevant is chemistry to atmospheric systems? How the interaction of molecules among themselves and interaction of molecules with light affects the gas phase surrounding planets? What tools can be used to understand the mechanisms operating in planetary atmospheres?
These are the questions that this laboratory aims to answer.

ACS Earth and Space Chemistry, Aug, 2024 Peer-reviewedCorresponding author<p id="p1">High-resolution and high-precision spectrum data presents a challengingmeasurement. We report newly measured ultraviolet absorptioncross-sections of 32SO2, 33SO2, 34SO2, and 36SO2 for the - band over thewavelength range 240 to 320 nm at a resolution of 0.4 cm−1. Theresolution is improved by 20 times compared to a previous study(Danielache et al., 2012). A least absolute deviation linear regressionmethod was applied to calculate the cross-sections and spectral errorsfrom a set of measurements recorded at a wide range of pressure toensure optimal signal-to-noise ratio at all wavelengths. Based on thisanalysis, error bars on the measured cross-sections ranged between 3 and10%. The overall features of measured cross-sections, such as peakpositions of isotopologues, are consistent with previous studies. Weprovide improved spectral data for studying sulfur mass-independentfraction (S-MIF) signatures in SO2 photoexcitation. Our spectralmeasurements predict that SO2 photoexcitation produces 33E = −0.8±0.2‰and 36E = −4.0±0.4‰, whose magnitudes are smaller than those reported byDanielache et al. (2012).</p>

Journal of Geophysical Research Atmospheres, 113(D17) D17314, Sep 16, 2008We report measurements of the ultraviolet absorption cross sections of < sup > 32 < /sup > SO < inf > 2 < /inf > , < sup > 33 < /sup > SO < inf > 2 < /inf > , and < sup > 34 < /sup > SO < inf > 2 < /inf > , recorded from 30,300 to 52,500 cm < sup > -1 < /sup > (330 to 190 nm) at 293 K with a resolution of 25 cm < sup > -1 < /sup > . The < sup > 33 < /sup > SO < inf > 2 < /inf > , sample was produced by the combustion of isotopically enriched < sup > 33 < /sup > S while the < sup > 34 < /sup > SO < inf > 2 < /inf > and natural abundance samples were obtained from commercial manufacturers. The spectrum of the natural abundance sample is in agreement with previously published spectra. The spectra of the isotopically pure species were retrieved using the isotopic composition of the samples. The < sup > 32 < /sup > SO < inf > 2 < /inf > , < sup > 33 < /sup > SO < inf > 2 < /inf > , and < sup > 34 < /sup > SO < inf > 2 < /inf > absorption spectra show rich vibrational structure, and the positions and widths of the peaks change with isotopic substitution i n a complex fashion. The results imply that large wavelength-dependent and broadband isotopic fractionations are associated with the UV photolysis of SO < inf > 2 < /inf > .
