Geometrical Derivatives of Energy Surfaces and Molecular Properties W. Vogel & M. Büttner GmbH 4Ergänzende Modelle51The development and computational implementation of analytical expres sions for the low order derivatives of electronic energy surfaces and other molecular properties has undergone rapid growth in recent years. It is now fairly routine for chemists to make use of energy gradient information in locating and identifying stable geometries and transition states. The use of second analytical derivative (Hessian or curvature) expressions is not yet routine,
