6-(4-methylbenzylamino)purine 2 , 6-(3,4-dimethoxybenzylamino)purine 3 , 2-chloro-6-(3-bromobenzylamino)-9-isopropylpurine 4 and 2-chloro-6-(3,4-dichlorobenzylamino)-9-isopropylpurine 5 have been investigated by means of single crystal X-ray diffraction analysis, FT-IR and Raman spectroscopy, and quantum chemical calculations, where HF, DFT, RI-MP2 and MP2 methods in combination with the cc-pVDZ basis set have been used
摘要 6-(2-methylbenzylamino)purine 1 , 6-(4-methylbenzylamino)purine 2 , 6-(3,4-dimethoxybenzylamino)purine 3 , 2-chloro-6-(3-bromobenzylamino)purine 的结构和光谱性质-9-异丙基嘌呤 4 和 2-氯-6-(3,4-二氯苄氨基)-9-异丙基嘌呤 5 已通过单晶 X 射线衍射分析、FT-IR 和拉曼光谱以及量子化学计算进行了研究,其中 HF、DFT、RI-MP2 和 MP2 方法与 cc-pVDZ 基组结合使用。将理论获得的结构和光谱参数与实验获得的参数进行了比较。不寻常的结构特征之一是发现 6-(2-methylbenzylamino)purine 1 的电中性形式在嘌呤环的 N7 位置质子化,
