Research

STRUCTURES OF MOLECULES FROM MICROWAVE SPECTROSCOPY
Microwave spectroscopy can provide detailed and accurate 3-D structures for many small molecules. These structures usually provide coordinates with accuracies of 0.01
for the free molecules in the gas phase. The gas phase structures can be directly compared with high-level theoretical calculations. For many cases additional splittings in the high-resolution spectra give information on quadrupole coupling and other interactions which provide details on the electronic charge distribution (where the electrons are) in the molecules. Pulsed-beam, Fourier-transform spectrometers provide the required sensitivity and resolution to make these measurements on a wide variety of molecules. The extremely high sensitivity and high resolution of the pulsed-beam, Fourier transform microwave spectrometer (Flygare-Balle spectrometer) systems have opened the door for numerous new structural measurements on larger and less stable molecules and complexes. One of these Flygare-Balle spectrometers has been working in our lab for 27 years and a new, much larger one has been in operation since 2010.
