查询词典 M-P

Atom, molecule or radical can be excited to a specific intermediate state by absorbing m laser photons, then the parent ion can be produced by absorption of another n laser photons. The ion yield can be increased drastically due to resonant absorption, comparing with the ion yield in non-resonant absorption. This multiphoton process is usully called Resonance Enhanced Multiphoton Ionization. REMPI technique plays an important role in detecting the high electronic excited states of atoms, molecules and radicals.

原子、分子、离子或自由基在同时吸收m个光子从下态共振跃迁到中间态后再吸收n个光子使其电离的过程中，下态和中间态的多光子共振吸收使得产生的离子信号强度比相应的非共振多光子电离得到的离子信号强度有很大的增强，该过程称为共振增强多光子电离REMPI。
