Real-time measurements of ultrafast electronic dynamics in the disproportionation of [TCNQ]22− using a visible sub-10 fs pulse laser

- Disproportionation of [TCNQ]22− to TCNQ and TCNQ2− proceeds in two steps.
- Photoexcitation of the TCNQ− dimer triggers an electron transfer (<10 fs).
- Dissociation to the products TCNQ and TCNQ2− proceeds within 350 fs.
- The decay time of the singlet excited state of TCNQ2− is about 900 fs.
