Abstract:

In this paper an improved method for calculating the 17O NMR chemical shift of hydroxyl group in carboxylic acids, including saturated and unsaturated fatty acids, benzyl acids, benzyl acetic acids, benzyl propenoic acids and amino acids, was discussed. A new parameter, Δα, was proposed for calculation.

Key words: 17O NMR, chemical shift, carboxylic acid, fatty acid, benzyl acid, benzyl acetic acid, benzyl propenoic acid, amino acid
