The methods of quantitative conformational analysis of cyclic
fragments in molecules and the computer
program RICON (RIng CONformations) developed by us for this purpose are
considered. Program RICON
uses atomic coordinates obtained from X-ray studies or force
field/quantum chemical computations and
allows one to analyze geometric parameters of a molecule, to compute
the puckering parameters of rings in
the molecule using various methods, and to obtain a verbal description
of a ring conformation. The abilities
of the program are described, and the examples of its application are
given.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
