XMVB

Xiamen Valence Bond (XMVB) is a quantum chemistry program based on valence bond (VB) theory. XMVB provides an ab initio computing platform for various VB approaches, including classical VB methods, such as VBSCF, BOVB, VBCI, VBPT2, modern VB methods, such as SCVB and GVB, and molecular orbitals based VB method, BLW. Combined with solvation models, it can perform VBPCM, VBEFP, and VBSMD to account for solvent effects. Incorporating XMVB with KS-DFT code, it can be applied to hybrid DFVB calculation.
