摘要

Several physical processes produce similar effects in electron paramagnetic resonance (EPR) spectroscopy that are often collectively characterized as exchange. One common description of the exchange effects is based on stochastic changes in the EPR frequency. This general treatment has been adapted and modified for each specific type of exchange. But the general treatment can provide insights into the mechanisms and appearance of exchange.
