New in 2012 through 2017
August 2012: ChemicaElectrica Gateway is released for the
first time replacing the ChemicaElectrica Database. New features
include a 3-d drawing program with the MM2 minimizer and MOPAC geometry
optimization, substructure and similarity searching, internet
connectivity and flexible menus. A new low price is also introduced for
this product. See our ChemicaElectrica Gateway
web page for details.
