| 摘 要： | 利用自行研制的脉冲直流放电装置产生SF2自由基，结合共振增强多光子电离(REMPI)技术，研究了27—294nm范围内SF2自由基(2+1)REMPI激发谱，获得了SF2自由基3d,5s里德伯态相应的带源及被激活的对称伸缩振动模的振动频率，并估算了这些态的量子亏损值．

| Abstract: | A pulsed dc discharge in a pulsed supersonic beam has been developed as an efficient source of producing free radicals. Spectra of the SF2 radical were observed between 272 and 294 nm by (2+1) resonance-enhanced multiphoton ionizition (REMPI) spectroscopy. Vibrational progressions associat-ed with 3d and 5s Rydberg states were assigned. The spectroscopic values ω＇1 (a1, symmetric stretch-ing), band origin T0 and quantum defect δ of these Rydberg states were reported. |
