摘要
本文测得二氯二茂锆和九种二氯二(取代茂)锆的红外和拉曼低频光谱,改进了二氯二茂锆的简正坐标计算和低频谱带的归属,并对有争议的Zr-Cp和Zr-Cl伸缩振动的归属进行了讨论。结果表明,茂环上的取代基对Zr-Cp和Zr-Cl键的力常数没有明显的影响。
The IR and Raman spectra of Cp_2ZrCl_2 and nine (R-Cp)_2ZrCl_2 (Cp=cyclopentadienyl) were measured. Normal coordinate analysis of the coordinate center of (R-Cp)_2 ZrCl_2 was carried out using reported molecular parameters. The Zr-Cp and Zr-Cl stretching frequencies were discussed and reasonably assigned. Vibration analysis indicates that the influence of the substitutions on cyclopentadienyling upon the stretching force constants of Zr-Cp and Zr-Cl is insignificant.
