丙炔的微波频谱经过严格审查，以获取适用于射电天文学的信息。将导出的旋转常数、离心畸变参数、超精细耦合常数、电偶极矩和分子结构等分子数据制成表格。观察到的旋转跃迁涉及天文学上有趣的同位素形式和丙炔的最低振动状态。计算出 12CH3 12C eq 12CH、13CH3 12C eq 12CH、12CH313C eq 12CH 和 12CH3 12C eq 13CH 的基振动态以及 12CH3 12C eq 12CH 的振动激发态 ν10 的旋转跃迁。
The microwave spectrum of propyne is critically reviewed for information applicable to radio‐astronomy. Molecular data such as the derived rotational constants, centrifugal distortion parameters, hyperfine coupling constants, electric dipole moment, and molecular structure are tabulated. The observed rotational transitions are presented for the astronomically interesting isotopic forms and the lowest lying vibrational state of propyne. Calculated rotational transitions are presented for the ground vibrational state of 12CH3 12C≡ 12CH, 13CH3 12C≡ 12CH, 12CH313C≡ 12CH and 12CH3 12C≡ 13CH, and for the vibrationally excited state ν10 of 12CH3 12C≡ 12CH.
