      The photoelectron spectrum of the 7,7,8,8-tetracyanoquinodimethane (TCNQ) radical anion has been measured at 3.1 eV. Additionally, the ultrafast relaxation dynamics of the first excited state (12B3u) of TCNQ have been studied using time-resolved photoelectron spectroscopy, which reveals that it undergoes internal conversion back to the ground state (2B2g) with an associated lifetime of 650 fs ...

    • Ultrafast Relaxation Dynamics Observed Through Time-Resolved Photoelectron Angular DistributionsPeer reviewedClosed access

      Article scientifique
      Time-resolved photoelectron imaging of the 7,7,8,8-tetracyanoquinodimethane (TCNQ) radical anion is presented. Photoelectron angular distributions (PADs) are qualitatively analyzed in terms of the simple s-p model that is based on symmetry arguments. The internal conversion dynamics from the first excited state (12B3u) to the ground state (2B2g) may be observed through temporal changes in the PADs ...
