The paper is devoted to the study of behavior of alkali metal ion in the cavity of crown ether membrane under the influence of external factors such as temperature and electric field. The studies were performed using a semi-empirical method AM1 and the molecular dynamics method in the tight binding approximation (MDTB). The object of investigation is molecular system of a cryptand-222 with encapsulated sodium ion. During the study it is revealed the presence of irregular oscillations for the sodium ion inside the cavity of cryptand. The paper proposes a mechanism for stabilizing the period (frequency) of the oscillation using an external electric field. It is shown that at the certain strength of the external field and the temperature charged ion can oscillate, accompanied by radiation in the terahertz range.
