摘要 用源调制微波谱仪和傅里叶变换微波谱仪观测了2π电基态线性C 5 D自由基的旋转谱线。测量了 173-279 GHz 区域的 48 条谱线和 11-16 GHz 区域的 10 条谱线，并通过最小二乘法确定了 10 个分子常数，包括超精细相互作用常数。计算射电天文观测中 C 5 D 的低 J 旋转跃迁频率。
Abstract The rotational spectral lines of the linear C 5 D radical in the 2 Π electric ground state are observed with a source-modulation microwave spectrometer and a Fourier-transform microwave spectrometer. Forty-eight spectral lines in the 173-279 GHz region and 10 in the 11-16 GHz region are measured and 10 molecular constants, including hyperfine interaction constants, are determined by a least-squares method. Frequencies of low- J rotational transitions of C 5 D are calculated for radio astronomical observations.
