High resolution FTIR spectra of the short lived species ketenimine have been recorded in the regions 390-1300 cm(-1) and 20-110 cm(-1) using synchrotron radiation. Two thousand six hundred sixty transitions of the ν(7) band centered at 693 cm(-1) and 126 far-IR rotational transitions have been assigned. Rotational and centrifugal distortion parameters for the ν(7) mode were determined and local Fermi and b-axis Coriolis interactions with 2ν(12) are treated. A further refinement of the ground state, ν(12) and ν(8) parameters was also achieved, including the treatment of previously unrecognized ac-axis and ab-axis second order perturbations to the ground state.
使用同步辐射，在 390-1300 cm(-1) 和 20-110 cm(-1) 区域记录了短寿命物种亚乙烯亚胺的高分辨率傅里叶变换红外光谱。已分配了中心在 693 cm(-1) 的 ν(7) 带的 2660 个跃迁和 126 个远红外转动跃迁。确定了 ν(7) 模式的旋转和离心扭曲参数，并处理了局部费米和 b 轴科里奥利相互作用与 2ν(12)。还进一步改进了基态、ν(12)和 ν(8)参数，包括处理以前未识别的基态的 ac 轴和 ab 轴二阶微扰。
