Abstract
The rotational dynamics of 3-(benzo[d]thiazol-2-yl)-7-(diethylamino)-2 H-chromen-2-one (3BT7D2H-one) in two non-polar solvents acetone and ethyl acetate have been studied with varying temperatures. The rotational dynamics follow follows the Stoke's-Einstein-Debye (SED) model in ethyl acetate solvent but shows deviation in acetone solvent when temperature is increased. Quasi-hydrodynamic models Gierer and Wirtz (GW) model and Dote-Kivelson Schwartz (DKS) is studied in a qualitatively way.
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
