Triplet-Exciton Pairs in Organic Crystals: Optical Properties of TIPS-tetracene

This collection contains the data associated to the thesis with the same name, and is most meaningful in combinatio with it. This thesis describes the results of optical experiments on crystals of the compound TIPS-tetracene (5,12-bis((triisopropylsilyl)-ethynyl)tetracene) at cryogenic temperatures (0.3-60 K), strong DC magnetic fields (0-30 T) and intense THz radiation (0.3-0.7 THz). The experiments were conducted at the HFML-FELIX facility of Radboud University, Nijmegen, the Netherlands. These extreme conditions allowed the study of strongly exchange-coupled triplet-exciton pairs and their role in singlet-exciton fission (SF).
