The paper shows the experimental results of destabilization kinetics of compound chelate structures - polyvinyl pyrrolidone-iodine in the field of low-frequency vibrations of 2 to 45 Hz. For various exposure modes we found optimal frequencies, at which the process rate was maximal. The article presents experimental data on the change in the Raman spectra of clathrate and chelate structures before and after the exposure to low-frequency acoustic vibrations of 10 Hz and intensity of 55 dB. Moreover, we identified an important feature of the studied clathrate and chelate structures that lead to their sensitivity to low-frequency exposure - a change of iodine state in the structure. Low-frequency vibration method allows us to study the impact of external influences on the state of biochemically active structures both of clathrate, and chelate type. The experimental data make it possible to make conclusions about the low-frequency energy effect on clathrate and chelate structures.
