表面单分子膜取向确定的垂悬液滴图像理论分析

本文建立了用于表面单分子膜研究的垂悬液滴球体球模型，据此模型，对具有荧光生色团的表面活性剂荧光分析，计算了荧光分析的偶极矩强度分布，分子密度分布以及荧光图象强度分布，具有对单轴对取向性的分子，推导出了全部Ｒａｍａｎ散射活性矩阵元，计算并绘制了Ｒａｍａｎ图象的光强分布和偏振光强比分布，给出了确定取向的荧光图像方法以及Ｒａｍａｎ图象方法。

Theoretic study of imaging for pendent drop used to determine orientation structure of monolayer film

In this paper,both fluorescent imaging and the Raman imaging method used to determine molecular orientation of LB film on pendent drop are proposed.Based on the globe model established by us,for the molecule which is of a chromophore,the distributions for dipole intensity of fluorescent surfactant molecules,for surfactant molecular density and for fluorescent intensity along the observed direction have been calculated,the formulae used to determine molecular orientation has been induced;for the molecule which is of uniaxial orientation,all of Raman activity matrix elements have been calculated,the intensity distribution of Raman imaging for pendent drop and the ratio distribution of polarized Raman intensity which is used to determining molecular orientation have also been calculated and drawn out
