Fig. 3: Experimental FSR spectra of Cy7 in aerated and degassed acetonitrile.

Experimental FSR spectra presented as a contour graph recorded in (a) aerated and (b) degassed acetonitrile. The extracted TR-Raman spectra of (c) Z3 Cy7, (d) Z4 Cy7, (e) T1 Cy7, (f) S1 Cy7, and (b) hot S1 states of Cy7. Experimental FSR spectra in (c–g) are shown as black lines, and the extracted TR-Raman spectra of the corresponding species are represented by colored-filled curves.
