Calculation of first-order one-electron properties using the coupled-cluster approximate triples model CC3

Abstract

The calculation of first-order one-electron molecular properties is discussed for the iterative approximate coupled-cluster triples model CC3. The implementation which has the computational scaling N7 uses an explicitly spin coupled excitation space. Sample calculations are presented for the quadrupole moments of ethylene where the largest calculation uses an aug-cc-pVQZ basis which contains 344 basis functions.
