Query: Deformation of an inner valence molecular orbital in ethanol by an
  intense laser field   Valence molecular orbitals play a crucial role in chemical reactions. Here we
reveal that an intense laser field deforms an inner valence orbital (10a') in
the ethanol molecule. We measure the recoil-frame photoelectron angular
distribution (RFPAD), which corresponds to the orientation dependence of the
ionization probability of the orbital, using photoelectron-photoion coincidence
momentum imaging with a circularly polarized laser pulse. Ab initio simulations
show that the orbital deformation depends strongly on the laser field
direction, and that the measured RFPAD cannot be reproduced without taking the
orbital deformation into account. Our findings suggest that the laser-induced
orbital deformation occurs prior to electron emission on a sub-optical-cycle
time scale.
