Infrared Spectra and Phototransformations of meta-Fluorophenol Isolated in Argon and Nitrogen Matrices

Infrared spectroscopy accurately identifies individual meta-fluorophenol conformers in cryogenic argon and nitrogen matrices, providing insights into conformational isomerism and UV phototransformations.

Conformational Space, IR-Induced, and UV-Induced Chemistry of Carvacrol Isolated in a Low-Temperature Argon Matrix.

Carvacrol in a cryogenic argon matrix shows four conformers, with two most stable, and irradiated with UV light leads to cleavage of the OH group, resulting in alkyl-substituted cyclohexadienones and subsequent photochemical transformation

Photoreaction of 2-chlorothiophenol studied by low-temperature matrix-isolation IR spectroscopy with DFT calculation

2-chlorothiophenol's photoreactions in Ne and Ar matrixes produce 2,4-cyclopentadien-1-ylidenemethanethione, while UV irradiation in Ar matrixes yields 4-chloro-2,5-cyclohexad

UV-Induced Photochemistry of 1,3-Benzoxazole, 2-Isocyanophenol, and 2-Cyanophenol Isolated in Low-Temperature Ar Matrixes.

UV-induced photochemistry of 1,3-benzoxazole in low-temperature argon matrixes leads to nearly quantitative conversion into 2-isocyanophenol, with isomeric 2-cyanophenol undergoing a [1,5] H-shift and unstable nitrile ylide isomer

Photoinduced Wolff rearrangement and tautomerization of 3-chloro-2-hydroxypyridine isolated in an Ar matrix

UV irradiation of 3-chloro-2-hydroxypyridine in an argon matrix leads to tautomerization, photodissociation, and the formation of a five-membered-ring ketene and HCl.
