Schatz Lecture

Paul N. Schatz has published widely in spectroscopic areas ranging from the study of absolute infrared intensities to Magnetic Circular Dichroism (MCD) measurements on matrix isolated species using Synchrotron Radiation in the vacuum ultraviolet, as well as on the theory of mixed valence compounds.

He was a pioneer along with Professor Philip J. Stephens in the development of Magnetic Circular Dichroism (MCD) spectroscopy. This included development of one of the first MCD instruments along with the theoretical interpretation of the novel data produced. These studies started with symmetrical inorganic molecules in solution, then moved on to symmetrical organic molecules, and then to crystals doped with such molecules at pumped liquid helium temperatures (~2.7 K) and as a function of temperature. In later years, matrix isolated species were studied, and pioneering studies on these species were carried out using far ultraviolet frequencies available at the Synchrotron Radiation Center in Stoughton Wisconsin.

Along with Professor S. B. Piepho, a comprehensive book emphasizing the group theoretical aspects of MCD was published in 1983.

In 1978, along with Professors S.B. Piepho and Elmars Krausz, the first rigorous theoretical treatment of the spectroscopy of mixed valence compounds was published. In what later became known as the PKS model, both spectroscopic and dynamic aspects of these compounds were explored in detail.
