Abstract:

This paper presents a new DEPT spectral editing method. Multivariate linear regression was used to analyze the spectra and calculate the best fitting coefficients. The obtained fitting results were then used to calculate DEPT subspectra, yielding separated CH3, CH2 and CH signals. The new spectral editing method was shown to perform well on DEPT spectra, especially the complex ones.

Key words: NMR, 13C spectral editing, DEPT, multivariate linear regression
