Nobel Laureate Roald Hoffmann To Deliver 2014 Kilpatrick Lecture

When: 

Sep 15, 3:00pm to 5:30pm

Where: 

MTCC Auditorium

Speaker: 

Nobel Laureate Roald Hoffmann
Cornell University

Description: 

Nobel Laureate Roald Hoffmann

The IIT Chemistry Division’s 2014 Kilpatrick Lecture, "All The Ways To Have A Bond," will be given by Nobel Laureate Roald Hoffmann of Cornell University on Monday, September 15 at 3pm in the MTCC Auditorium. In his work in applied theoretical chemistry, Hoffmann looks for interesting experimental results which he can explore with computational methods in order to construct generalized models and frameworks for understanding. He was awarded the 1981 Nobel Prize jointly with Kenichi Fukui "for their theories, developed independently, concerning the course of chemical reactions."

Chemistry Division Executive Associate Chair Ishaque Khan notes, “We recognize the increasing power and importance of computation in chemistry, and have just hired two faculty working in this area. We are extremely pleased to have Professor Hoffmann as our Kilpatrick Lecturer as it emphasizes our excitement about and commitment to computational chemistry.”

Hoffmann, who is the Frank H. T. Rhodes Professor of Humane Letters Emeritus at Cornell, is renowned not only for his scientific expertise, but also for his ability to share the beauty and mystery of science with the general public through poetry, prose, and theater. He has published several books, plays, and volumes of poetry, and is well known as an engaging and thought-provoking lecturer. This will be Hoffmann’s second visit to IIT; he also gave the Kilpatrick Lecture in 1973, and he is one of seven Nobel Laureates who have delivered a Kilpatrick Lecture. The Kilpatrick Lecture is held annually in honor of Martin Kilpatrick, who chaired the IIT chemistry department from 1947–1960. The Kilpatrick Lectures are open to the public.

Abstract

The concept of a chemical bond, so essential to chemistry, and with a venerable history, has life, generating controversy and incredible interest. Even if (or maybe because) we can’t reduce it to physics. I will discuss some of the common experimental criteria for judging the presence and strength of a bond: length, energy, force constants, magnetism, energy splittings and other spectroscopic criteria. On the theoretical side, I will look at bond orders, population analyses, bond critical points, and electron localization functions. And will give a personal opinion on the utility of the various measures. My advice at the end is likely to be: Push the concept to its limits. Think about any bond in terms of all the various criteria, experimental and theoretical, that we have discussed. Accept that (at the limits) a bond will be a bond by some criteria, maybe not others. Instead of wringing your hands about how terrible it is that this concept cannot be unambiguously defined, have fun with the fuzzy richness of the idea. Try to understand what motivates other people to say there is a bond there or isn’t. Always think about what change (chemical perturbation) you can do to probe your ideas.
