摘　　要：用染料激光激发钾蒸气 ,观察到了与钾分子电子态 5 3 Πu 振动能级相关的电离谱 ,根据电离谱峰对应的激光波长值计算出了钾分子 5 3 Πu 态的振动结构常数 。The ionization spectra associated with the vibration energy level of 5 3Π u state of molecular potassium were observed when the potassium vapor was excited by a dye laser. The vibration constants were calculated according to the laser wavelengths. It is consistent with the theoretic result calculated by Magnier and Millié within the experimental error.
