Important Contributions

Development of methods in quantum chemistry and theoretical spectroscopy. Specific contributions to the understanding of :

• the transcorrelated method
• the long range behaviour of Hartree-Fock orbitals
• semiclassical methods for vibrational energies
• the variational method for rovibrational wavefunctions (in normal and internal coordinates)
• Full configuration interaction with Slater determinants (benchmark studies)
• convergence of the Møller-Plesset series
• the reaction path Hamiltonian
• Anharmonic spectroscopic and thermodynamic properties using higher derivative methods
• Brueckner-doubles theory
• Open shell Møller-Plesset theory
• frequency-dependent properties
• Density functional theory : quadrature, new functionals and molecular properties.
