Web10 Aug 2010 · Restricted open-shell Hartree-Fock (ROHF) theory is formulated as a projected self-consistent unrestricted HF (UHF) model by mathematically constraining spin density eigenvalues. The resulting constrained UHF (CUHF) wave function is identical to that obtained from Roothaan's effective Fock operator. WebRestricted open-shell Hartree–Fock ( ROHF) is a variant of Hartree–Fock method for open shell molecules. It uses doubly occupied molecular orbitals as far as possible and then singly occupied orbitals for the unpaired electrons. This is the simple picture for open shell molecules but it is difficult to implement.

Web5 Nov 2024 · The rate of moderate to severe chronic GVHD for Orca-T patients was 4% vs. 44% in the SoC cohort (p=0.016). In a preliminary subset of evaluable Orca- T patients, GVHD & relapse free survival (GRFS) at one year was higher for Orca-T patients vs SoC (69% versus 33%, p=0.006) while relapse and overall survival did not appear to differ. WebMulticonfigurational self-consistent field (MCSCF) methods go beyond the single-determinant Hartree-Fock (HF) method by allowing the wave function to become a linear combination of multiple determinants.
