中文摘要：

采用直流脉冲高压对SO2／He（配比1：99，总压强3．0×10^5Pa）混合气体放电产生SO超声分子束，SO自由基由彭宁电离其前体SO2再解离而形成．发射光谱中350-500nm波长范围的电子振动谱标识为SO（A′^3△→X^3∑^-）跃迁，通过对实验谱线拟合，获得了该跃迁的带源v00=29524（8）cm^-1，SO（A′^3△）的光谱常数ω′e=742（6）cm^-1，ω′eχ′e=5．9（2．0）cm^-1，以及基电子态的光谱常数ω″e=1165（5）cm^-1,ω″eχ″e=6．4（0．5）cm^-1．

英文摘要：

The sulfur oxide radical （SO） molecular beam was generated by DC pulsed discharging the SO2 seeded in helium with the ratio of 1：99 at total pressure of 3.0 ×10^5 Pa in the supersonic expansion. The emission spectrum in the range of 350-500 nm was assigned to the A′^3△→X^3∑^- system of SO. The generation of SO free radical was interpreted to be Penning ionized from its precursor SO2 then further dissociated. Analyzing the medium resolution SO vibronic spectra, the molecular constants of the states of SO involved in the transition are determined to v00=29524（8）cm^-1,ω″e=1165（5）cm^-1,ω″eχ″e=6.4（0.5）cm^-1,ω′e=742（6）cm^-1,ω′eχ′e=5.9（2.0）cm^-1.
