Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science and related areas. It offers a flexible rendering framework and a powerful plugin architecture.

功能： A. 晶体坐标变换 -分数坐标和直角坐标互转 -向ａ,ｂ,ｃ三个方向堆积i,j,k个晶胞 -按给定对称关系得出所有相关原子 -按空间群对称性由不等价原子推出晶胞内所有原子 -查看空间群信息及对称等价位置 -自动转换*.cif文件 B. 分子坐标变换 -按指定对称操作任意平移、旋转、反映或反演当前的坐标 - 将一组坐标的中心平移到原点 -自动点群识别 -自动调整分子取向，包括 1)自动将分子的主轴调整到x,y,z轴上 2)自动将分子的自定义的某个轴调整到自定义的另外一个轴上 C. 各种文件格式的转换 注：Windows Vista使用注意：将cartes.exe的兼容模式改成Windows XP，并从用“管理员运行模式”

This project is a small program using Qt for calculation and visualization of electron charge densities in crystals and molecules. It can create a 2D plane of charge densities or create a 1D representation of the charge densities along a given line, in both cases it can also export the graphical representations to various image formats. The program can import various file formats such as space 3D grids of charge density values, created in a quantum chemistry programs Gaussian, Crystal and VASP. ...

NLOPredict is a nonlinear optical prediction and data analysis tool. Nonlinear optical measurements can yield information about the structure of crystals, and orientation of molecules at surfaces and interfaces.
