Abstract

It has been found out that milimetre-wave (MMW) radiation in the37.5-78 GHz range affected spectral properties of aminoacids,nucleotides, proteins and nucleic acids in free and intracellularstates. MMW radiation effect was detected by the infrared (IR)spectrum parameter changes such as intensity, halfwidth and shape ofabsorption and reflection bands. It was established that tuned MMWaction upon intensity of IR reflection bands had sharp resonance withhalfwidth of 40-60 MGHz, that corresponded to Q-quality of order 1000.For high ordered systems such as aminoacid single crystals MMW effectdetection depended strongly on orientation of the mm-field electricalvector relative to symmetry axes of object.
