本文用不可约张量方法给出了描述非线性开壳层分子在外电场或磁场作用下微波谱的一般理论。这一理论为讨论非线性自由基状态之间的电偶极跃迁的可能检测提供了基础。在8.3和8.7 GHz之间的自由基HCO在小磁场中的aK-加倍跃迁的四个组件的检测和光谱分析的理论提出的前面。从这种分析结果的分子参数进行了比较与从固态研究中获得的。
A general theory for the description of the microwave spectra of nonlinear open-shell molecules in the presence of external electric or magnetic fields is presented using irreducible tensor methods. This theory provides the basis for discussion of the possible detection of electric dipole transitions between states of a nonlinear free radical. Detection of the four components of aK-doubling transition in small magnetic fields for the free radical HCO between 8.3 and 8.7 GHz is described and the spectrum is analysed in terms of the theory presented earlier. The molecular parameters which result from this analysis are compared with those obtained from solid-state studies.
