| Abstract: | The Near-infrared Fourier-transform Raman Spectroscopy and two-dimensional correlation analysis method were applied to study an oxidation process of the solid ascorbic acid at 100℃ It is shown by study results that the microcosmic information of a change in dynamic structure can be provided for ascorbic acid during oxidation process An important theory reference was fist proposed to produce a transition state of ascorbic acid anion in an oxidation process of ascorbic acid |
