Resonance response of vibrational transitions in amino acid crystals to millimeter radiation

摘要

Abstract: Results of study of resonance interaction of low-energy radiation in the interval of 37 - 53 GHz with $beta@-alanine and $alpha@-glycine monocrystals have been presented. The role of form-factor effect was investigated. It was revealed that the MMW irradiation of aminoacid crystal in a process of infrared reflection spectra registration led to considerable intensity redistribution and to bands thin structure manifestation of the deformational vibrations of NH$+3$PLU$/ and CO$+2$MIN$/ groups near 15000 cm$+$MIN@1$/. Resonance character of millimeter wave influence was determined. In the action spectra numerous resonances with the halfwidths from 40 to 80 MHz were observed.!6
