Calculations and electron spin resonance spectra of syringic and sinapinic acid

摘要

Syringic acid (3,5-dimethoxy-4-hydroxybenzoic acid) and sinapinic acid (3,5-dimethoxy-4-hydroxycinnamic acid) are used as model compounds to correlate electron spin resonance (ESR) spectral data with structural and spin distribution information obtained from ab initio (Gaussian94) calculations. ESR spectra and computational results will be used to interpret the antioxidant activity of natural phenolic compounds. (C) 2000 John Wiley & Sons, Inc. [References: 18]
