Here we report a study on the photophysics of a series of N-phenyl-carbazoles (N-Ph-Czs) in homogenous solvents and micellar media. The compounds investigated were TCz (N-tolyl-carbazole), TCz-TCz (a 3,3´-linked dimer), ...

We have implemented an electron-nuclear real-time propagation scheme for the calculation of transient absorption spectra. When this technique is applied to the study of ultrafast dynamics of Soret-excited zinc(II) ...

Photoreduction of 3-phenylquinoxalin-2-ones, XNQ, by triethylamine, TEA, gives a metastable semireduced quinoxalin-2-one via an electron-proton-electron transfer, with unit quantum yields at high amine concentrations. ...

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 ...

The absorption-spectral and kinetic behavior of radical ions and triplet states of two oxoisoaporphine derivatives, 2,3-dihydrooxoisoaporphine (2,3-DHOA) and 5-methoxy-2,3-dihydrooxoisoaporphine (5-MeO-2,3-DHOA), have been ...

The paper shows an alternative methodology to calculate transmission line parameters per unit length and to apply it in a three-phase line with a vertical symmetry plane. This procedure is derived from a general procedure ...

Photoreduction by amines of oxoisoaporphine dyes occurs via a stepwise mechanism of electron-proton electron transfer that leads to the metastable N-hydrogen oxoisoaporphine anion. During photoreduction that occurs from ...

A method for the analysis of line profiles based in the pseudo-Fano function was developed, which results of more simple application than the Voigt function usually employed in Spectroscopy to represent the line shapes. A ...
