To investigate the temporal dynamics of EMT in greater detail, we analyse the SBSs of two consecutive snapshots separated by 2 fs on either side of the transition (Figure ). At both 3.0 and 6.0 MPM we see large changes in the bands close to the Fermi level occurring during the flipping despite the fact that the atomic positions and electron densities right before and after the flip remain very close to each other. This indicates that the flipping is induced by only small changes in molecular geometries leading, nevertheless, to significant temporal fluctuations in the band gap, which appears to be just enough to switch between metallic and electrolyte behaviour. In other words, the width and degree of filling of the band gap in the present system turns out to be very sensitive to small changes in molecular geometry and the associated electron density distribution.
