Within time-dependent Hartree–Fock theory, we study the CO ionization for six different photon wavelengths running from 200 to 700 nm. The parallel and perpendicular alignments of the CO molecular axis with the polarization direction of the laser electric field are considered for two different laser intensities, namely and W cm⁻². At the laser intensity W cm⁻², the ionization picture is characterized by the dominance of the highest occupied molecular orbital, while at laser intensity W cm⁻² the inner valence molecular orbitals significantly contribute to the CO ionization. The present computations also reveal that orbital switching effects due to peak intensity variation may occur at some shorter wavelengths.

在与时间相关的 Hartree-Fock 理论中，我们研究了从 200 到 700 nm 的六种不同光子波长的CO电离。平行和垂直对准CO与激光电场的偏振方向分子轴被认为是两个不同的激光强度，即和w ^厘米^-2。在激光强度W cm ^{-2 下}，电离图像的特点是最高占据分子轨道占主导地位，而在激光强度W cm ^{-2 下}，内价分子轨道对CO 有显着贡献电离。目前的计算还表明，由于峰值强度变化可能会在一些较短的波长上发生轨道切换效应。
