Abstract
A theoretical study of the orientation-dependent attoclock shift in photoelectron momentum distributions generated by ionization of HeH+ by a counter-rotating two-color bicircular laser field is presented. Solutions of the two-dimensional time-dependent Schrödinger equation are extrapolated to the adiabatic limit and compared to two-step trajectory models. The trajectory models are sensitive to the choice of the tunnel exit point, which depends on the dipole moment and polarizability tensor of the molecule. Using a suitable trajectory model, we are thus able to reconstruct these molecular properties from the momentum distributions within about 7% deviation from the exact values.
