“…(246) A correlation of vibrational frequencies calculated from the force constants is in good general agreement with the observed frequencies, (337) although there are some discrepancies between the vibrational assignments and those made by Prima (319) and by Lord and Miller.

“…At least six photons at 800 nm (1.55 eV) are required to ionize the furan. Seven photons suffice to populate the next higher cation state D 1 at 10.31 eV [27] from energy consideration. For minimizing photon processes of order higher than 6, the laser intensity for the ionization pulse has been chosen to be about 1×10 12 W/cm 2 resulting in a minimally disentangled photoelectron image (Figure 1 (a)).…”

Ultrafast photodynamics of furan has been studied by time-resolved photoelectron imaging (TRPEI) spectroscopy with an unprecedented time resolution of 22 fs. The simulation of the time-dependent photoelectron kinetic energy distribution (PKED) has been performed with ab initio nonadiabatic dynamics "on the fly" in the frame of time-dependent density functional theory. Based on the agreement between experimental and theoretical time-dependent photoelectron signal intensity as well as on PKED, precise time scales of ultrafast internal conversion from S(2) over S(1) to the ground state S(0) of furan have been revealed for the first time. Upon initial excitation of the S(2) state which has π-π* character, a nonadiabatic transition to the S(1) state occurs within 10 fs. Subsequent dynamics invokes the excitation of the C-O stretching and C-O-C out of plane vibrations which lead to the internal conversion to the ground state after 60 fs. Thus, we demonstrate that the TRPEI combined with high level nonadiabatic dynamics calculations provide fundamental insight into ultrafast photodynamics of chemically and biologically relevant chromophores.
