Recently, through the use of one-electron excitation operators, the set of low-lying excited states of several electronic systems was obtained within the framework of the Hermitian Operator method combined with the ...

The calculations carried out with the G-particle-hole hypervirial equation (GHV) method for a set of ground-states dominated by a single determinant of electronic systems have yielded highly-accurate results when compared ...

High accuracy energies of low-lying excited states, in molecular systems,have been determined by means of a procedure which combines the G-particle-holehypervirial (GHV) equation method (Alcoba et al. in Int J Quantum Chem ...

The G-particle-hole hypervirial (GHV) equation has been recently reported (Valdemoro et al., Sixth International Congress of the International Society for Theoretical Chemical Physics Vancouver: Canada, 2008. Alcoba et ...

By applying a matrix contracting mapping, involving the G-particle-hole operator, to the matrix representation of the N-electron density hypervirial equation, one obtains the G-particle-hole hypervirial (GHV) equation ...

We have recently (Valdemoro et al., Sixth International Congress of the International Society for Theoretical Chemical Physics, 2008; Alcoba et al., Int J Quantum Chem, in press) reported the form of the G-particle-hole ...
