在v1 = 1，v2= 1和2，v3 = 1的激发振动态下，确定了臭氧的微波吸收光谱。在v_1 = 1和v_3 = 1态，观测到了由于强Coriolis相互作用引起的反常现象。定义了Coriolis扰动态的惯性亏损，并成功地应用于分析。确定了科里奥利耦合常数ε 13 c为0.60，并由此导出了二次力常数。立方势常数（和三阶力常数），确定从振动-旋转相互作用常数。四次势常数是由McCaa和Shaw的振动非谐常数导出的。在臭氧、二氧化硫和二氟化氧的非谐势常数之间观察到密切的相似性。得到了基态和激发振动态的平衡结构和平均结构。
Microwave absorption spectra of ozone were identified in the excited vibrational states withv1= 1,v2= 1 and 2, andv3= 1. In thev1= 1 andv3= 1 states, an anomaly due to a strong Coriolis interaction was observed. The inertia defect in the Coriolis perturbed states was defined and successfully applied to the analysis. The Coriolis coupling constantζ13cwas determined to be 0.60, from which the quadratic force constants were derived. The cubic potential constants (and third-order force constants) were determined from the vibration-rotation interaction constants obtained. The quartic potential constants were derived from the vibrational anharmonic constants by McCaa and Shaw. Close similarities were observed among the anharmonic potential constants of ozone, sulfur dioxide, and oxygen difluoride. The equilibrium structure and average structures in the ground and excited vibrational states were obtained.
