The spectra of polar molecules can be measured in absorption or emission by microwave spectroscopy or by far infrared spectroscopy.

The molecular geometry of both rotamers can be obtained experimentally by high resolution infrared spectroscopy augmented with in silico work.

Infrared spectroscopy has been used extensively to distinguish between isomers.

The core themes of his work are supercritical fluids, infrared spectroscopy and lasers.

Infrared spectroscopy of surface sites and adsorbed molecules can then be used to monitor the change in the vibrational frequencies upon adsorption.
