Abstract: A new method is proposed for the determination of the complete 2D NOESY mixing coefficient matrix from the peak intensities of nonsymmetric 2D NOESY in which its overlapping peak intensities are included.The method was confirmed with numerical simulated studies.The method makes full use of the nonsymmetric 2D NOESY overlapping peak intensities in calculating the full 2D NOESY mixing coefficient matrix.This may benefit the accurate measurement of internuclear distances in such complex spin systems as biomacromolecules.

Key words: Nonsymmetric 2D NOESY, Overlapping peak, 2D NOESY mixing coefficientmatrix
