Geometry optimization using generalized, chemically meaningful constraints.
An external geometry optimizer (BOptimize) is described that can be used together with a number of existing quantum-chemical codes (Gaussian, Gamess-UK, Turbomole, ADF, Orca, Priroda, Spartan-PM3, Mopac) and allows flexible and general constrained optimizations. Some details of the implementation are discussed, and examples are provided of constrained optimizations that would be difficult or impossible to perform with existing optimizers.
