Diverse Applications of Two-Dimensional Correlation Spectroscopy (2D-COS)

Applied Spectroscopy, Journal Year: 2024, Volume and Issue: unknown

Published: June 4, 2024

This second of the two-part series a comprehensive survey review provides diverse applications two-dimensional correlation spectroscopy (2D-COS) covering different probes, perturbations, and systems in last two years. Infrared has maintained its top popularity 2D-COS over past Fluorescence is most frequently used analytical method, which been heavily applied to analysis heavy metal binding, environmental, solution systems. Various other methods including laser-induced breakdown spectroscopy, dynamic mechanical analysis, differential scanning calorimetry, capillary electrophoresis, seismologic, so on, have also reported. In years, concentration, composition, pH are main effects perturbation fields, as well temperature. Environmental science especially studied using 2D-COS. shows that undergoes continuous evolution growth, marked by novel developments successful across scientific fields.

Aqueous Photosensitization of Syringaldehyde: Reactivity, Effects of Environmental Factors, and Formation of Brown Carbon Products

ACS Earth and Space Chemistry, Journal Year: 2024, Volume and Issue: 8(6), P. 1193 - 1203

Published: May 18, 2024

Phenolic aldehydes as brown carbon (BrC) chromophores may contribute to the mass of aqueous secondary organic aerosol (aqSOA) due their potential atmospheric photosensitizers. However, there is still a lack knowledge about sensitizing ability and impact environmental factors. In this work, we studied photosensitized behavior phenolic aldehyde, syringaldehyde (SyrAld), in solutions. Under illumination, influences factors such precursor concentration, solution pH, codissolved inorganic constituents (NaCl Na2SO4), matter (vanillyl alcohol, VAL, methoxyphenol produced during biomass burning) were investigated. Our results show that increasing pH salt concentration causes strong red shift absorption peak SyrAld, chloride salts sulfate exert different effects on photochemical reactivity SyrAld. Interestingly, opposite SyrAld VAL oxidation observed at wavelengths light. UV-B irradiation, inhibited degradation by light shielding effect, while under UV-A photosensitization promoted degradation. The major photooxidation products identified hydroxylated induced reactive oxygen species (OH radicals) dimerized direct triplet excited state (3SyrAld*) using UPLC-Q-TOF-MS. This work suggests play significant roles determining fate waters.
