Applications of π-photon-induced transparency in two-frequency pulse electron paramagnetic resonance experiments

Abstract

Bichromatic pulses were demonstrated to substitute the second mw source both in stimulated soft electron spin echo envelope modulation (SS-ESEEM) and four-pulse double electron-electron resonance (DEER) experiments. As such, the results were compared to those obtained using traditional techniques. The behavior of bichromatic pulses which fulfill the transparency or near-transparency condition was investigated, and recommendations for obtaining optimum results were given.
