Movie showing evolution of the electron hole density (left) near a conical intersection of CO2 molecule. The corresponding changes in the nuclear wavepacket due to bending and assymetric stretching motion are also shown (right). For details see our Physical Review Letters paper
UA physicists led by Arvinder Sandhu (right) take advantage of the attosecond laser pulses to take snapshots of chemical reactions.
