| Abstract: | The substituent effect on the UV spectra of the 2-substituted styrylbenzothiazole has beenstudied. It is observed that the spectra undergo a red .hift as the conjugative effect of substituentsbecomes stronger. It is obtainted a good linear relationship between the shift of UV of p-substitutedcompounds and conjugation effect. |
