Files are all .txt format and can be read in any standard text editor. Organization is by publication Figure as the raw data here underlies the figures found in the following publication: Title: Observation of Strongly Exchange-Coupled Triplet Pairs in an Organic Semiconductor Journal: Nature Physics Note: all data is given in preprocessed format #### Files for Figure 1 ##### Description: Temparature dependent transient ESR spectral slices taken at 300ns after laser flash in TIPS-Tetracene spin coated films. Labelling: Files labelled by temperature following "Figure-1c-TEMPERATURE.txt" where the temperature at which data was taken is given in Kelvin with all other experimental factors held constant (see publication for details) Files: 1. Figure-1c-10K.txt 2. Figure-1c-20K.txt 3. Figure-1c-30K.txt 4. Figure-1c-50K.txt 5. Figure-1c-75K.txt 6. Figure-1c-100K.txt 7. Figure-1c-150K.txt 8. Figure-1c-300K.txt #### Files for Figure 2 #### Description: Figure 2 files are taken from Figure 1c: Files: Figure 2b: "Figure-1c-10K.txt" Figure 2a: "Figure-1c-300K.txt" #### Files for Figure 3 #### Description: Echo intensity measured as a function of initial pulse length (Rabi oscillations) taken at triplet (~3700G) and quintet (~3535 G) frequencies at 10 K in thin film (TF) and macrocrystalline (MC) samples. Header provides column references for time and field position for the echo intensity. Labelling: files are labelled with TF or MC to indicate sample type and with field positions in Gauss for X-band nutation experiments. Files: 1. Figure-3b-Rabi-MC.txt 2. Figure-3b-Rabi-TF.txt #### Files for Figure 4 ##### Description: at triplet (T) and quintet (Q) frequencies at 10 K in thin film Lifetime Experiments: trESR intensity measured as a function of time after laser flash Echo Decay Experiments: Echo intensity measured as a function of interpulse delay (tau) taken at triplet (T) and quintet (Q) frequencies at 10 K in thin film (TF) and macrocrystalline (MC) samples. Labelling: files are labelled with TF or MC to indicate sample type and with field positions in Gauss for X-band nutation experiments and indicated in lifetime experiments with # in the header of the file.
