Abstract The THz spectra of amino acids after application of spots of acetone were measured. The 0.6 THz band was commonly observed in many amino acids that formed the intra‐molecular salt structure. The band can be attributed to the interaction vibration from the common structural configuration of amino acids and acetone molecules. The evidence suggests that the vibration between the amino acids with intra‐molecular salt structure and acetone has a peak at 0.6 THz. A model of the interaction vibration of acetone and the functional groups of amino acids is proposed. © 2006 Wiley Periodicals, Inc. Biopolymers 85: 207–213, 2007.
