Fuzzy Recognition of NMR Spectra Based on the Maximum Principle of Membership
摘要
Abstract
The principle and method of fuzzy recognition of NMR spectra based on maximum principle of membership were reviewed. The concept of fuzzy set for NMR spectra was first introduced, and then the membership function was given. By establishing library of standard compounds and algorithm of fuzzy recognition, a quick automatic qualitative analysis was achieved. 1H NMR spectra of 11 mixed samples composed of 4 compounds were analyzed. The results show that the compounds in the samples can be recognized accurately even when the peak positions were only calculated roughly, and the threshold of average membership took value from 0. 45～0.85.关键词
