摘要：

Ascorbic acid was investigated by FT-NIR (Fourier transform near-infrared) spectroscopy and generalized two-dimensional (2D) correlation spectroscopy. The FT-NIR spectra were measured over a temperature range of 30-130 degrees C. Combined near-infrared spectroscopy and generalized 2D correlation spectroscopy, the molecular structure (especially the hydrogen bond) was analyzed, four kinds of intermolecular hydrogen bond and two kinds of intramolecular hydrogen bond of ascorbic acid were elucidated, the bands of ascorbic acid were assigned. The results will be helpful to the understanding of ascorbic acid and utility of this substance. (c) 2006 Elsevier B.V. All rights reserved.
