butadiene-1,4- d 2 have been extended and improved from investigations of their Raman spectra as well as their infrared (IR) spectra. High-resolution IR spectra have been recorded for the three isotopomers, and a rotational analysis has been completed for strong bands of each species. Ground state and some upper state rotational constants have been fit. Corresponding ground state moments of inertia compare
摘要 合成了 1,4-d 2
丁二烯的反式、反式和顺式、顺式形式的样品,发现其中含有有用数量的作为污染物的顺式、反式种类。通过对其拉曼光谱和红外 (IR) 光谱的研究,对
丁二烯-1,4-d 2 的三种同位素的基本频率分配进行了扩展和改进。已经记录了三种同位素的高分辨率红外光谱,并且已经完成了每个物种强谱带的旋转分析。基态和一些高态旋转常数已经拟合。相应的基态转动惯量与从 B3LYP/6-311++G** 理论获得的平衡转动惯量相比更胜一筹。正在制备两种 13 C 同位素异构体,
