摘要
利用飞行时间质谱仪研究了ＣＨ３Ｉ分子在４４０—５１０ｎｍ波段的多光子电离（ＭＰＩ）机理．在该波段，ＣＨ３Ｉ分子吸收三光子激光能量与（５ｐπ，６ｐ）里德伯态高频端发生共振，然后继续吸收光子电离解离成最终产物离子．
AbstractThe multiphoton ionization spectrum of methyl iodide is studied in the 440—510nm region.Three photon is just resonant with the high frequency tail of the (5pπ,6p) Rydberg state of methyl iodide.Then the excited methyl iodide continually absorbs another photon to be ionized and dissociated into fragment ions.
