Scientific paper

Coulomb explosion imaging has been used to explore anisotropies in the fragment angular distribution associated with the symmetric six-electron Coulomb explosion channel of C O2 and N O2 induced by 100 fs , 1015 W/ cm2 radiation at 800 nm and leading to doubly charged atomic ions. Specific precursor molecular geometries (bond angles prior to explosion) and orientations of the molecular axis (the line connecting the two outer atoms in the system) relative to the polarization axis were isolated for analysis by exploiting the correlation among the atomic ions ejected simultaneously. The effective orientation of the precursor molecular axis is preferentially along the polarization axis for both C O2 and N O2 with respective distributions and widths of cos39 θ (Δθ≃22°) and cos25 θ (Δθ≃27°) , which are substantially narrower than that of H2 , cos19 θ (Δθ≃31°) . The widths and distributions are found to be nearly independent of bond angle over a wide range of bond angles (35° and 55° for C O2 and N O2 , respectively). The narrowing of the width of the distribution from H2 to C O2 , combined with the independence of bond angle are consistent with (1) an increasing moment of inertia, (2) an increasing final charge state, and (3) an increasing precursor molecular ion ionization stage.
