Calvin College Physics and Astronomy Department will host a seminar entitled “The Third Chemical Bond: An Introduction to Ligand Field Theory, Electron Paramagnetic Resonance, and Magnetic Circular Dichroism” presented by Jackson Ross on Tuesday, November 6 at 3:45 pm in SB 110.  Please join us to hear about his research into ligand bonds.

Ligand bond interactions represent a third type of chemical bond: while covalent interactions share electrons, and ionic bonds operate on the coulombic force between charged ions, the ligand bond is a donation of electrons to unfilled orbitals, usually of a metal atom. These bonds are highly pervasive in nature, and occur in most environments where metals and non-metals interact. Synthetically, organometallic complexes form the cutting edge of material science research into superconductors and catalysts. Studying these compounds has been a major focus of inorganic chemistry for many decades, but improvements in instrumental techniques has opened up the field of ligand chemistry to condensed matter physics. Using electron paramagnetic resonance and magnetic circular dichroism, the structure, electronics, and energy states of ligand complexes can be determined, giving vital insight to theories of complex bonding and material interaction.

Refreshments will be served at 3:30 in SB 157
