以前未报道的带烯丙基，烯丙基-d5，2-甲基烯丙基自由基已被检测到的质量分辨，共振增强多光子电离光谱。聚焦在480和535 nm之间的激光诱导双光子吸收，制备自由基的3s 2A，Rydberg态。吸收两个额外的光子使被激发的自由基电离。烯丙基和2-甲基烯丙基自由基的这些电子态分别位于40085和38369 cm-1。未观察到分子离子的后续碎裂。
Previously unreported bands of allyl, allyl-d5, and 2-methylallyl radicals have been detected by mass-resolved, resonance-enhanced multiphoton ionization spectrometry. Focused laser light between 480 and 535 nm induced two-photon absorptions preparing the 3s 2A, Rydberg states of the radicals. Absorptionof two additional photons ionized the excited radicals. These electronic states of allyl and 2-methylallyl radicals lie at 40085 and 38 369 cm" 1 11, respectively. No subsequent fragmentation of the molecular ions was observed.
