Abstract
A method of resolution enhancement of high resolution nuclear magnetic resonance spectra of polymers which are poorly resolved due to large local viscosity, is proposed. This method is a suitable subtraction of the second derivative of the spectra from original ones, and one which can be carried out automatically with the aid of a chart reader and a computer. A moderate value for the proportionality constant to the second derivative is obtained as K=1–2. The effect of the separation between representative points at the reading to the computer is also discussed. This procedure is applied to the NMR spectra of poly (methyl propenyl ether).
