Ascorbic acid, infrared absorption spectrum

Figure 4.6 Infrared absorption spectrum of phosphomolybdenum blue solution (a) reduced with ascorbic acid and antimony (giving maximum absorbance at 882 pm), (b) reduced with tin(II) chloride, (c) reduced with ascorbic acid. Reprinted from Analytica Chimica Acta 27, Murphy, J. and Riley,...

B. The infrared absorption spectrum of a potassium bromide dispersion of the sample exhibits maxima at the same wavelengths as those of a similar preparation of USP Ascorbic Acid Reference Standard. 

Infrared analysis of L-ascorbic acid yields a spectrum with a number of interesting absorptions (Figure 3.9).
