He was awarded the status of Fellow in the American Physical Society, after he was nominated by the Division of Chemical Physics in 1990, for "significant contributions to molecular spectroscopy, particularly the elucidation of intramolecular relaxation in intermediate molecules, and the development of laser-induced phosphorescence spectroscopy and ultrahigh-resolution spectroscopy in supersonic jets". He is a fellow of the American Association for the Advancement of Science and a member of the American Chemical Society.
