Abstract

A simple algorithm for optimising the orbitals for single open-shell configurations which utilises a sequential unconstrained minimisation technique (SUMT) suggested by Morrison is presented in this paper. As numerical illustrations, the orbitals of the lowest π - π* singlet and triplet (Ms = 0) states of three conjugated hydrocarbons are optimised by the algorithm. The advantages of using the SUMT method are also emphasised.
