Abstract Raman (resonance Raman, FT-Raman), IR and UV-visible spectroscopy and quantum chemistry calculations were used to investigate the photodissociation dynamics of furfural in S2 state. The resonance Raman(RR) spectra indicate that the photorelaxation dynamics for the S0→S2 excited state is predominantly along nine motions: C=O stretch ν5 (1667 cm-1), ring C=C antisymmetric stretch ν6 (1570 cm-1), ring C=C symmetric stretch ν7 (1472 cm-1), C2-O6-C5 symmetric stretch/C1-H8 rock in plane ν8 (1389 cm-1), C3-C4 stretch/ C1-H8 rock in plane ν9 (1370 cm-1), C5-O6 stretch in plane ν12 (1154 cm-1), ring breath ν13 (1077 cm-1), C3-C4 stretch ν14 (1020 cm-1), C3-C2-O6 symmetric stretch… More >
