摘　　要：本工作通过变温实验获取化合物(分子式为C_(16)H_(16)N_(2) FBr)理想的1D,2D核磁共振谱图,在此基础上顺利地完成该化合物的结构确定。随后,又利用HMR的实验结果求算出该化合物的转环速率及其能垒,为该化合物合成线路的设计合理性和进一步研究提供依据。With the experiments of variable temperature(VT),the ideal 1D and 2D NMR spectra were obtained for the compound (molecula formula:C15H16N2 FBr),and the structure of this compound was successfully elucidated. Then the data of the experiments were used to caculate the rate constant of exchang at coalescence and the energy barrier for the compoud as well.
