Chemical Shift Types of protons 9.0-6.0 Aromatic 4.6-6.6 Olefinic 4.0-0.5 Aliphatic 4.0-2.0 CH3, CH2 and CH protons α to aromatic range 2.0-1.0 CH2 and CH protons of alkyl chains or further to the ring and CH3 protons β to the ring 1.0-0.5 CH3 protons of alkyl chains γ or further from aromatic ring or CH3of saturated compounds
