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 3.0×105 Pa in the supersonic expansion. The emission spectrum in the range of 350-500 nm was assigned to the A'3→X3∑- 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 be ν00 = 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.
