Descrição geral

Xylenes is the mixture of isomeric ortho-, meta- and para-forms of xylene. Its dispersed emission and time of flight mass spectra has been reported. Transitions from S1 ↔ S0 states have been found to be within the range of 100cm-1 and were reported to be arising due to the internal rotation of ring methyl groups. Time-resolvedin situ FTIR spectroscopic and gas chromatographic studies have been carried out to study its diffusion coefficients, adsorption rates and isomerization efficacy over HSZM-5 surfaces.

Aplicação

Xylenes may be employed in chloramphenicol acetyltransferase (CAT) assay to evaluate the CAT gene expression.
