Spectra structure correlation of some p-Nitrobenzylphenyl ethers

ABSTRACT

Infrared and NMR spectra of some mono- and di-substituted p- nitrobenzylphenyl ethers were studied to investigate the effect of substitution, in the phenyl moiety, on the spectral features of the molecule. Bands due to gamma C-H of benzylic protons were assigned and correlated with the electron releasing ability of the substituents. The relative chemical shifts of the CH2 in the HNMR spectra of the benzylphenyl ethers [delta delta] in DMSO solutions were also correlated with the substituent constant
