Experimental study of relaxation processes in solid solutions of nitrogen-ethanol observed in the process of raising the temperature of the film is carried out. Our previous studies have found that the state of the film is not stable. The increase of cry matrix temperature leads to changes in the vibrational spectrum of ethanol. This article focuses on determining the effect of ethanol concentration in the nitrogen matrix on the investigated relaxation processes. Measurements were carried out in a temperature range from 12 to 40K, the pressure in the vacuum chamber was less than 5×10-8Torr. The concentration of ethanol in nitrogen was varied in the range from 0.5% to 3%. Conclusions are made based on the analysis of thermo grams and said that increase the concentration of ethanol in nitrogen leads to the beginning of the relaxation processes at lower temperatures. This is explained by the presence in nitrogen cryomatrix of ethanol polyaggregates with larger size.
