WolframChemistry/ ChemistryFunctions

Wolfram Language functions for Chemistry

Contributed by: Jason Biggs, Wolfram Research

This package provides a wide range of capabilities for chemists, biochemists, and anyone else who works with molecular structures. These functions expand upon the existing chemistry functions built into the Wolfram Language. With functions for substructure matching, joining molecules, and visualization, as well as dynamic controls and predicate functions, this package can help you explore and analyze molecules in new and powerful ways.
