Lowest energy triplet states of furan, studied by high resolution electron energy loss spectroscopy

Résumé

The excitation spectrum of furan has been recorded between 3 and 6.2 eV by high resolution electron energy loss spectroscopy at 30 eV incident electron energy and scattering angles of 10° and 25°. The lowest energy singlet–triplet transitions are confirmed to be responsible for two bands centred at 3.97 eV (3B2) and 5.15 eV (3A1), respectively. Vibrational structure is resolved for the first time in the 3A1 band and its analysis has provided identification of the excited state normal modes and their energy.
