Abstract

The NMR and fluorescence quenching of benzene, chlorobenzene and methoxybenzene in acetonitril and 2-propanol solvents have been carried out with a view to understand the quenching mechanisms. The quenching is found to be appreciable and shows positive derivation in the stern-volmer plots. UV absorbance is used to measure the excitation wavelength. Lifetime measurements are carried out and the quenching rate constant kq is also calculated. Molar extinction co-efficient, stoke's shift are also calculated. The NMR study is used to conform if there is any complex formation between 1-methylindole with the benzene derivatives.
