利用Ar/CF4、Ar/CF2Cl2或Ar/CF3COOH混合气体的直流脉冲放电产生CF自由基，观测了260～360nm范围内转动分辨的CF自由基双光子共振增强多光子电离谱。分析表明，该段光谱对应于CF自由基3pπD2Πr(ν'=2～6,r=3/2,1/2)←←X2Πr(ν"=0,r=3/2,1/2)的共振激发。对观测的振动带进行了转动分析，并获得了3p里德堡态的转动常数和自旋-轨道分裂值。

CF radicals were generated by using a dc discharge in the mixture of Ar/CF4,Ar/CF2Cl2,and Ar/CF3COOH.The rotationally resolved(2+1)resonance-enhanced multiphoton ionization(REMPI)spectra of CF radical have been investigated in the wavelength range 260～360nm.The analysis shows that the observed spectra can be assigned as the two-photon resonance excitation 3pπD2Πr(ν'=2～6,r=3/2,1/2)←←X2Πr(ν"=0,r=3/2,1/2).The related rotational constants and the spin-orbit splitting values of CF 3p Rydberg state have been derived.
