摘要：

We describe the linear version of the spin adapted coupled cluster theory with all single and double excitations for open shell systems in restricted Hartree-Fock formalism. The method is based on the partitioning of the Hamiltonian developed by Hubac and Carsky [I. Hubac and P. Carsky, Phys. Rev. A 22, 2392 (1980)] in restricted Roothaan open shell formalism. Correlation energy of some simple molecular systems is calculated.
