Within the framework of this project, experimental and theoretical studies of the structure and properties of various highly reactive intermediates and unusual molecules are carried out at temperatures of liquid helium. The original approaches and methods used in the work make it possible to obtain unique information of interest to various branches of chemistry and chemical physics, in particular, radiation chemistry and photochemistry, chemistry of interstellar space, terrestrial and planetary atmospheres, as well as for the development of new principles for manipulating chemical reactions at low temperatures. Of independent interest is the possibility of obtaining and studying the properties of a new class of compounds with unusual chemical bonds – noble gas hydrides of the general formula HNgX. The studies use a combination of highly informative methods of IR and EPR spectroscopy under conditions of matrix isolation, quantum-chemical calculations of the modern level are used.
