Early work in theoretical polarography (with J. Koutecký) on polarographic kinetic currents and experimental work in high-resolution optical spectroscopy (with D. A. Ramsay) leading to the first analysis of the rotational fine structure of the electronic spectra of a truly polyatomic molecule and a determination of the first singlet excited state geometry of glyoxal.
His principal work concerns quantum chemical methodology and its applications (several with J. Čížek):
