The photostability and photophysical properties of the dimethyl ester of the mycosporine-like amino acid shinorine have been experimentally evaluated in aqueous solution and in the presence of direct micelles prepared with ...

A combined matrix isolation FTIR and theoretical DFT/B3LYP/6-311++G(d,p) study of the molecular structure and photochemistry of 1-(tetrazol-5-yl)ethanol [1-TE] was performed. The potential energy surface landscapes of the ...

Polyphenolic substances synthesized by plants are generally involved in protection against UV radiation and the attack of pathogenic microorganisms. Resveratrol (3,5,4′-trihydroxystilbene, RSV) is synthesized in its ...

Phytochromes are photosensitive proteins with a covalently bound open-chain chromophore that can switch between two principal states: red light absorbing Pr and far-red light absorbing Pfr. Our group has previously shown ...

A combined matrix isolation FT-IR and theoretical DFT(B3LYP)/6-311++G(d,p) study of the molecular structure and photochemistry of 5-ethoxy-1-phenyl-1H-tetrazole (5EPT) was performed. A new method of synthesis of the compound ...

The five-membered heterocyclic γ-butyrothiolactone was isolated in a low-temperature, inert Ar matrix, and the UV−visible (200 ≤ λ ≤ 800 nm)-induced photochemistry was studied. On the basis of the IR spectra, the formation ...

The Photochemical Research Group from San Luis (Argentina) highlights the contributions of Dr. Norman Andino García to the development of the group as a way to show him our gratitude for all his support.

The magnetic field effect (MFE) on the emission spectrum, phosphorescence lifetime and quenching by phenols were investigated for the tris(1,10 phenantroline) chromium (III) complex ([Cr(phen)3]3+). The reactions in the ...
