Diatomic molecule in a strong infrared laser field level-shifts and bond-length change due to laser-dressed Morse potential /
We present a general mathematical procedure to handle interactions described by a Morse potential in the presence of a strong harmonic excitation. We account for permanent and field-induced terms and their gradients in the dipole moment function, and we derive analytic formulae for the bond-length c...

| Tartalmi kivonat: | We present a general mathematical procedure to handle interactions described by a Morse potential in the presence of a strong harmonic excitation. We account for permanent and field-induced terms and their gradients in the dipole moment function, and we derive analytic formulae for the bond-length change and for the shifted energy eigenvalues of the vibrations, by using the Kramers-Henneberger frame. We apply these results to the important cases of H-2 and LiH, driven by a near- or mid-infrared laser in the 10(13) W cm(-2) intensity range. |
