摘要: The coupled cluster method, which is based on the exponential Ansatz for wave operator, found a particularly fertile ground in quantum chemical investigations of molecular electronic structure, where many-electron correlation effects play crucial role and this approach became method choice, when handling nondegenerate states. objective contribution to provide brief historical perspective some current challenges methodology outline most recent attempts at their solution.
