Francis J. Lovas (Assoc)

Research interests

The measurement and assignment of radio frequency, microwave and infra-red spectra of low to high temperature species.

Research objectives

Molecular structure studies of transient species, and van der Waals or hydrogen-bonded complexes and studies of isolated molecules of particular interest to radioastronomy in interstellar and circumstellar clouds. Primary spectroscopic instruments employed are Fourier transform microwave spectrometers using supersonic nozzles and electric discharges.

Current research interest


  • George van Biesbroeck Prize from the American Astronomical Society, 1998
