Description
Summary:[Display omitted] •Vibrational spectroscopy reveals dynamic ion behavior.•Review organizes theoretical insights and methodologies.•Experimental work on vibrational relaxation in various ionic systems is presented. In recent years, there has been a boom in the publication of research results on ionic (electrolyte) systems used in the creation of electrochemical energy systems (batteries, supercapacitors, etc.). One of the alternative ways to obtain dynamic information in ionic systems is spectroscopic experiments, and the most valuable information on the behavior of condensed systems at picosecond and adjacent time intervals is provided by vibrational spectroscopy. The source of this information is the analysis of the shape and width of the lines in the vibrational spectra of ion systems. This review aims to systematize the theoretical and methodological aspects of the study of the dynamics of ion systems by vibrational spectroscopy.
