The common absorbency in acidic solutions is in the vicinity of 3030 cm"1 (NH3+), 2130 cm"1 (NHS+), and 1730 cm-1 (COOH); in alkaline solutions, it is 3300 cm-1 (NH2), 1610 cm"1 (COO"), and 1400 cm"1 (COO-). These absorbency bands show the ionic form of the amino acid in each solution, ie, in solid or in solution, of the isoelectric point, which is the evidence that the amino acid exists as a dipolar ion. Common absorbencies at 1450 cm-1, 1370 cm-1, and 1330 cm-1 are attributed to C-N and C-H and do not vary with change in pH.
