Early work in theoretical polarography (with J. Koutecky) on polarographic kinetic currents and experimental work in high-resolution optical spectroscopy (with D. A. Ramsay) leading to the first rotational analysis of a truly polyatomic molecule and the determination of the first singlet excited state geometry of glyoxal.
His principal interest and work concerns the development of quantum chemical methodology. Major contributions include (several with J. Čížek):
