NO2 的 A 2B2 和 X 2A1 态的电偶极矩通过高分辨率激光光谱在超声速分子束中在高达 300 kV/cm 的静电场下测量。测量是在 593 nm 处对带 99 的 qR(0)00 跃迁进行的。激发态 (101) 的结果为 μb(J’ = 1/2)=0.278(6)D，μb(J’ = 3/2)=0.254(6)D，基态 (000) 的结果为 μb=0.289(6)D。未知背景态对斯塔克图案的扰动可能局限于 210 kV/cm 左右的场强。
Electric dipole moments of the A 2B2 and X 2A1 states of NO2 were measured by high resolution laser spectroscopy in a supersonic molecular beam under a static electric field ranging up to 300 kV/cm. The measurements were performed on the qR(0)00 transition of band 99 at 593 nm. The results for the excited states (101) are μb(J’ = 1/2)=0.278(6)D, μb(J’ = 3/2)=0.254(6)D and for the ground state (000) is μb=0.289(6)D. A perturbation of the Stark pattern by an unknown background state could be localized at field strengths around 210 kV/cm.
