Spectroscopic behavior of loratadine and desloratadine in different aqueous media conditions studied by means of TD-DFT calculations
(Elsevier, 2013-06)
In this study, we explained the influence of the stepwise protonation of two antihistaminic drugs on their experimental absorption spectra. We demonstrated the capability of the TD-CAM-B3LYP method, combined with a ...
Study of relative stability of tautomeric forms of phenylbutazone and calculation of UV-Vis and ECD spectra
(Brazilian Chemical Soc, 2016-01-01)
In this work, a theoretical study was carried out to investigate the electronic structures of the deprotonated form of phenylbutazone. Considering a relaxed PES scan from three selected dihedral angles (delta(1), delta(2), ...
TD-DFT calculations of UV absorption bands and their intensities in the spectra of some tetrahydroquinolines
(Royal Society of Chemistry, 2015-03-04)
A detailed analysis of the MOs involved in electronic transitions in UV spectra as well as a conformational study of 1-benzenesulfonyl-1,2,3,4-tetrahydroquinoline (BSTHQs) derivatives have been carried out using the TD-DFT ...
An experimental and TD-DFT theoretical study on the photophysical properties of Methylene Violet Bernthsen
(Elsevier, 2014-07)
We revisited the photophysics the Methylene Violet (MV) Bernthsen dye in aprotic solvents to rationalize both its peculiar solvatochromism, which cannot be explained by the standard solvatochromic empirical models, and the ...
