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 the understanding of a 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 trEPR spectroscopy. Besides that, it serves as documentation of software developed and maintained by the author of the website.
The theory section of this website contains references to the general literature about EPR and trEPR spectroscopy. A recent review by the author of this website covers its application in the field of organic semiconductors with a particular focus on triplet states, but starts with a general overview of the method.
