取代基的诱导效应、共轭效应、磁各向异性效应和立体效应对莨菪烷化合物杂环上氢核和碳核的化学位移有较大的影响。

Raman spectrum, UV-Vis spectra, IR, NIR and XPS spectra were used to characterize the material. The result indicates that there is a conjugative effect between MWNT and bromine, which induces the change of electron distribution on the MWNT surface. It increased the car- rier density and the electrical conductivity of MWNT became higher.

通过拉曼光谱，紫外可见光谱，红外吸收光谱，近红外吸收光谱和X光电子能谱等方法研究，结果表明：溴与多壁碳纳米管之间存在共轭作用，使多壁碳纳米管表面的电子云分布发生了变化，导致空穴载流子的产生，增加了载流子浓度，提高了多壁碳纳米管的导电性能。

The IR result shows that conjugative effect is the reason for the red shift of stretching vibration frequency for carbonyl, meanwhile hydrogen bonds lead to the red shift of stretching vibration frequency for hydroxy groups.

红外振动光谱结果发现，共轭效应导致了羰基伸缩振动频率红移，氢键的存在导致了羟基伸缩振动频率红移。

The hydrolysis of chitin under concentrated alkali conditions would produce double anion because of conjugative effect and steric effect (producing primary amine which had positive ion properties and linear chain macromolecular structure and which has good flocculability and clarification performance).

因共轭效应和空间效应，甲壳质在浓碱条件下水解，能形成双负离子，形成具阳离子性质的伯胺和具有直链高分子结构，具有优良的絮凝性能和澄清作用。

PS, NIR, UV and Raman spectra indicated that there was conjugative effect between MWNT and bromine which induced the movement of π electrons from MWNT to bromine to increase the hole carrier density.
