摘　　要：通过3光子激发I2,观察到了340mm紫外荧光谱。经过理论计算和电离谱分析,确认340nm是F′0+u→1Πg跃迁产生的。When I2 was excited by three-photon to get a visible B0+u←X1Σ+g transition followed by a simultaneous two-photon absorption, the UV fluorescence spectra at 340nm is observed This fluorescence spectra is identified as F′0+u→1Πg(1g) transition using Frank-Condon factor calculations and analysis of ionization spectra
