چکیده

The root-mean-square libration amplitude derived from non-rigid-body thermal motion analysis of 6-N,N-diacetylaminochrysene and 2,4-dinitrobenzoic acid predicts torsional frequencies in satisfactory agreement with the Raman spectra. Translational and librational lattice frequencies of the whole molecules derived from the L and T components are generally consistent with the spectroscopic results.

Localized surface plasmon resonance immunoassay and verification using surface-enhanced Raman spectroscopy

This work exploits the localized surface plasmon resonance (LSPR) spectroscopy of noble metal nanoparticles to achieve sensitive and selective detection of biological analytes. Noble metal nanoparticles exhibit an LSPR that is strongly dependent on their size, shape, material, and the local dielectric environment. The LSPR is also responsible for the intense signals observed in surface-enhanced...

Spectrophotometric Determination of Diazepam in Pure form, Tablets and Ampoules

The interaction of diazepam with picric acid (I), 3,5-dinitrobenzoic acid (II) and 2,4-dinitrobenzoic acid (III) was found to be useful for its spectrophotometric determination. The quantitation was carried out at 475, 500, and 500 nm for the reaction with (I), (II) and (III), respectively. The effect of several variables on the coloring process was studied. The proposed methods have been appli...

Unusual co-crystal of isonicotinamide: the structural landscape in crystal engineering.

The idea of a structural landscape is based on the fact that a large number of crystal structures can be associated with a particular organic molecule. Taken together, all these structures constitute the landscape. The landscape includes polymorphs, pseudopolymorphs and solvates. Under certain circumstances, it may also include multi-component crystals (or co-crystals) that contain the referenc...

Metabolism of 2,4-dinitrotoluene, 2,4-dinitrobenzyl alcohol and 2,4-dinitrobenzaldehyde by rat liver microsomal and cytosol fractions.

The metabolism of 2,4-dinitrotoluene (2,4-DNT), 2,4-dinitrobenzyl alcohol (2,4-DNB) and 2,4-dinitrobenzaldehyde (2,4-DNAI) in rat liver microsomal and cytosol fractions was investigated. The objectives of these studies were to determine whether 2,4-DNAI, a potent mutagen, is produced in the oxidation of 2,4-DNB to 2,4-DNBA and to clarify the nature of the enzymes responsible for the oxidation o...

Quenching of tryptophan fluorescence in the presence of 2,4-DNP, 2,6-DNP, 2,4-DNA and DNOC and their mechanism of toxicity.

Although they are widely used as insecticides, acaricides and fungicides in the agriculture or as raw materials in the dye industry, dinitrophenols (DNPs) are extremely noxious, death cases having been registered. These compounds produce cataracts, lower leucocyte levels, disturb the general metabolism and can cause cancer. It is also assumed that DNPs hinder the proton translocation through th...
