Abstract

Diffusion ordered 2D nuclear magnetic resonance spectroscopy (DOSY) is a molecular structure analysis method, and it is formulated as the non-negative matrix factorization (NMF) problem. This paper proposes a novel algorithm to solve NMF for DOSY based on the affine approximation approach. Simulation results show that the proposed algorithm achieves a high factorization performance and low calculation cost.
