Abstract

Abstract: The complete relaxation matrix analysis method was used to process the peak intensity matrix of phase sensitive NOESY spectrum of nervosin. The cross relaxation rates between proton pairs were obtained by diagonalizing the peak intensity matrix of NOESY spectrum and the inter-proton distances in nervosin molecule were calculated according to 1/r_tf⁶∝σ_tf. The calculated results of complete relaxation matrix analysis method are in agreement with the inter-proton distances calculated by molecular mechanics and determined by single crystal X-ray diffraction method.

Key words: Relaxation matrix, NOESY, Inter-proton distance, Nervosin
