Identification of transferred coherence. Comparison of impulsive Raman spectra directly generated in ¹TT (bottom, purple) and transferred from S₁ via singlet fission (top, blue, reproduced from Fig. 2). Experimental spectra are normalised to the high-frequency peak at 1392 cm⁻¹, which is truncated for clarity. Arrows indicate regions where singlet fission increases the peak (coherence) intensity. Dashed vertical lines are a guide to the eye indicating the dominant vibrational modes
