CW (Continuous Wave) EPR has traditionally been used to explore chemical reaction involving paramagnetic species such as free radicals and transition metal ions. Examples of applications are polymerization reactions, catalysis, and monitoring ROS (Reactive Oxygen Species). Often the reaction kinetics are too fast and CW EPR does not have sufficient time resolution. In this webinar we will demonstrate how Rapid Scan EPR offers the required faster time resolution to identify and monitor multiple species in the reaction. The results yield insights into the reaction mechanism as well kinetics.
This webinar starts with an introduction into Rapid Scan EPR and its advantages over the traditional CW EPR technique. After the introduction, the time resolved Rapid Scan experiment is introduced that we will be using in our examples. Several examples of fast chemical reactions are presented that have been studied by the technique.
This webinar will be especially useful for EPR users working on chemical and biological reactions such as ROS, catalysis, and polymerization. It will be useful to people that wish to explore how EPR can be used in the study of free radical reactions.
