RT Journal Article T1 Control defeasance by anti-alignment in the excited state A1 Chang, Bo Y A1 Shin, Seokmin A1 González Vázquez, Jesús A1 Martín, Fernando A1 Malinovsky, Vladimir S A1 Sola, Ignacio R AB We predict anti-alignment dynamics in the excited state of H2+ or related homonuclear dimers in the presence of a strong field. This effect is a general indirect outcome of the strong transition dipole and large polarizabilities typically used to control or to induce alignment in the ground state. In the excited state, however, the polarizabilities have the opposite sign compared to those in the ground state, generating a torque that aligns the molecule perpendicular to the field, deeming any laser-control strategy impossible.
