Time-resolved electron paramagnetic resonance (trEPR) spectroscopy, sometimes called transient EPR spectroscopy, is a special kind of electron paramagnetic resonance (EPR) spectroscopy. It allows for directly detecting (spin-polarised) paramagnetic intermediates. Often, these intermediates are optically induced species such as radical pairs and triplets. trEPR spectroscopy contributes sustantially to a variety of systems of both, biological and non-biological origin.
The idea of this website is to give an overview of methodological aspects as well as the underlying theory of time-resolved EPR. Besides that, it serves as documentation of software developed and maintained by the author of the website.
