The variationwith time of the electronic spectra of the basic dyes methylene blue and neutral
red in the presence of montmorillonite and hectorite clays has been studied to obtain …

We present a quantum-mechanical study on the solvent effects in the structure and
electronic spectra of some cationic dyes: acridine orange, proflavine, safranine, neutral red …

Proflavine, having the molecular formula C 13 H 11 N 3, is a well-known urinary antiseptic
and anticancer medication (3, 6-diaminoacridine). In this communication, Quantum chemical …

A study of the possible intersystem crossing (ISC) mechanisms (S⇝ T) in thionine (3, 7-
diamino-phenothiazin-5-ium), which is conducive to the efficient population of the triplet …

We have examined the electronic and molecular structure of 3, 7-diaminophenothiazin-5-
ium dye (thionine) in the electronic ground state and in the lowest excited states. The …

Attempting to unravel mechanisms in optical probing of proteins, we have performed pilot
calculations of two cationic chromophores acridine yellow and proflavin located at …

In this work we present a quantum-mechanical study on the structure and electronic spectra
of three cationic dyes monomers and dimers: acridine orange (AO), proflavine (PF) and …

Photophysical and photochemical properties of the dye resazurin were measured. The
quantum yields of fluorescence and triplet formation were determined to be 0.10±0.01 and …

The photosensitized aquation of pentaammine (pyridine) ruthenium (II) by several dyes has
been studied under conditions where only the sensitizers absorb light. The ratio of the …

In this work, the energy transfer by dipole-dipole interaction between cationic dyes in n-
alcohols (methanol, ethanol, 1-propanol and 1-butanol) is studied by time resolved and …
