Steric and mesomeric interaction factors on the electronic spectra of some nitrocresols

The electronic absorption spectra of some mono and di-substituted phenols OHC[6]H[3]XY, where X = NO[2] and Y= CH[3], in 90 percent aqueous ethanol and also in presence of 0.1 N NaOH or 0.1 N HC1 solutions were studied. The spectral behaviour in relation to the different interaction factors between the phenoxy group and the substituent were discussed
