Fig. 3: Reconstruction of attosecond charge migration in CO\({}_{2}^{+}\).
From: Filming movies of attosecond charge migration in single molecules with high harmonic spectroscopy

a Snapshots of the reconstructed hole densities for the alignment angle of 0°. b Enlarged views of the results in (a) in the range from x = −1.2 a.u. to x = 1.2 a.u. c HOMO, HOMO-1, and HOMO-2 orbitals of CO2 molecule. d Flux of charge density crossing the x = 0 (red) and y = 0 (blue) planes. Positive value means charge migration from +x (+y) side to −x (−y) side.
