This dataset contains the raw temperature dependent fluorescence decays measured using a FLS980 (Edinburgh Instruments) with the F980 software, the raw magnetic field dependent fluorescence- and CSS-Decays measured using a self-build ns-TA-spectrometer based on a LP920 setup (Edinburgh Instruments) and the raw fs-transient absorption data measured using a Helios pump-probe spectrometer (Ultrafast Systems). This dataset also contains DFT-optimized geometries and SQA-hyperfine couplings that were calculated using Gaussian16.
