bond softening : ウィキペディア英語版 | bond softening Bond softening is an effect of reducing the strength of a chemical bond by strong laser fields. To make this effect significant, the strength of the electric field in the laser light has to be comparable with the electric field the bonding electron "feels" from the nuclei of the molecule. Such fields are typically in the range of 1–10 V/Å, which corresponds to laser intensities 1013–1015 W/cm2. Nowadays, these intensities are routinely achievable from table-top Ti:Sapphire lasers. ==Theory== Theoretical description of bond softening can be traced back to early work on dissociation of diatomic molecules in intense laser fields.〔André D. Bandrauk and Michael L. Sink "Photodissociation in intense laser fields: Predissociation analogy" ''J. Chem. Phys.'' 74 1110 (1981)〕 While the quantitative description of this process requires quantum mechanics, it can be understood qualitatively using quite simple models.
