Two-dimensional laser-induced fluorescence (2D-LIF) spectra are reported for a set of features in the S1 ↔ S0 electronic spectrum of m-fluorotoluene. Two transitions previously assigned to fundamentals are reassigned in the present work. The main reassignments are confirmed with zero-electron-kinetic-energy (ZEKE) spectroscopy. Interactions in the S0, S1 and D0+ electronic states involving vibrational and vibration-torsional (“vibtor”) levels are identified via observed activity. The obtained vibrational wavenumbers compare well to the results of quantum chemical calculations.

解开间氟甲苯中的振动-振动和振动-扭转相互作用
二维激光诱导荧光（2D-LIF）光谱报道在S的一组特征1 ↔小号0的电子光谱米-fluorotoluene。先前分配给基础的两个过渡在当前工作中重新分配。零电子动能 (ZEKE) 光谱证实了主要的重新分配。S 0、S 1和D 0 +电子状态中涉及振动和振动扭转（“振动器”）水平的相互作用通过观察到的活动来识别。获得的振动波数与量子化学计算的结果相当。
