Chemistry Seminar Series 291 (4/26/19)

April 26, 2019 - 1:30pm

Kristi Closser, CSU Fresno

Abstract:

High energy electronic excitations (>10 eV) have unique characteristics that make them particularly challenging to model computationally. This talk will primarily focus on two projects related to application of quantum chemical methods to better understand high energy excited states and their photodegradation products. The first topic is focused on the absorption of extreme ultraviolet (EUV, ~92 eV) light by organic molecules, which is directly relevant for developing photoresist materials for the next-generation of photolithography. The other, more exotic, systems to be discussed are small helium clusters, which principally break apart when exposed to high energy radiation, but can also form stable excited states.
