Theoretical Study on the Long-lived Complexes for the Na＋I2 Collision System

For the Na I2 collision system, theoretical study is performed on the QCISD(T) level by using ab initio method. The ab initio potential energy surfaces are got and on them the long-lived complexes are found and optimized. These results verify the crossed molecule beam experimental phenomenon and the detailed geometry structures are given for the first time. The role of the complexes in the reaction path is also described in detail.

多官能团分枝状化合物的合成研究 Ⅳ.三方向醚-酰胺键型分枝状大分子的合成

本文报道三方向醚-酰胺键型多官能团分枝状大分子(Cascade)的合成.目标化合物以甘油、硝基甲烷为三方向起始核心,以从季碳原子三倍对称分散的化合物1～3为分支侧链.通过醚键进行空间延伸,以酰胺键进行分枝连接,经过一代或两代,所合成的分枝状大分子的末端官能团数是原起始核心的三倍或九倍.本文可为进一步的分枝反应提供基本的设计合成方法.     

LB膜混合聚集体中极性基团相互作用对光学非线性的影响

通过紫外－可见吸收光谱、压力－面积等温线、二次谐波的测量，研究了不同活性分子混合聚集体的形成对ＬＢ膜光学性质的影响。分子极性基团间的相互作用，使激发态能量及平均偶极矩发生变化，导致ＬＢ膜的光学非线性明显地增强或减弱。

对溴分子在６８８００－７２００ｃｍ＾－１范围内的两个被观察到的［＾２Π３／２］４ｄ偶宇称里堡态的转动光谱进行了计算模拟，确定了转动常数，并且证实了原先对实验光谱的传动结构和电子角动量的标识。     

分子和金表面相互作用的第一性原理研究

从第一性原理出发利用密度泛函理论研究了 4 ,4′ 二巯基联苯分子和金表面的相互作用 ,并利用了前线轨道理论和微扰理论定量地确定了该相互作用能常数. By using density functional theory, we have investigated the interaction between a thiol-phenyl molecule (4-4′-dimercaptodibenzene) and a gold surface. The frontier orbit theory and the perturbation theory are also employed to determine quantitatively the constant of interaction energy. The results show that the bonding between the sulfur atom and the gold atoms corresponds mainly to the covalent bond and some molecular orbits are extended over the molecule and gold cluster which certainly give channels...
