Abstract

We investigate the construction of an ultra-fast laser probe to determine the response of the electron dynamics of ethane using next generation QTAIM (NG-QTAIM). This is undertaken by applying a pair of simulated left and right circularly polarized ultra-fast laser pulses of duration 10 fs. A proportional increase in the C-C BCP bond strain with peak electric field was discovered. NG-QTAIM was used to identify a characteristic morphology associated with ultra-fast laser probes. Candidate ultra-fast laser probes were selected on the basis of the ground state population remaining undisturbed at a time t = 15 fs.
