摘要：

A new implementation of the density matrix renormalization group is presented for ab initio quantum chemistry. Test computations have been performed of the dissociation energies of the diatomics Be-2, N-2, HF. A preliminary calculation on the Cr-2 molecule provides a new variational upper bound to the ground state energy. (C) 2001 American Institute of Physics.
