In this study, the structure of systems synthesized based on biuret and nitric acid at different molar ratios (1:0.25; 1:0.5; 1:0.75)was investigated using infrared (IR) spectroscopy. The obtained results revealed the presence of intermolecular interactionsmanifested as shifts in the vibrational frequencies of the N–H, C=O, and N=O functional groups. It was established that with anincrease in the content of nitric acid, hydrogen bonding becomes stronger, proton exchange processes occur, and structuralreorganization of the system takes place. The most pronounced changes were observed at the 1:0.75 ratio. The results of the studyare of significant importance for substantiating the complex structure of these systems and their potential practical applications.
