- 配合物oh键的伸缩频率与形成配合物的构型有关。
The frequency of the OH stretching vibration is closely related to the geometric configuration of the complex. - H-O氢键的形成使复合物中水分子H-O键对称伸缩振动频率减小(红移)。
The H-O symmetric stretching modes of water in complexes are red-shifted relative to that of the monomer water. - SimpleDB是一个简单的数据存储,它缺乏一个完全成熟的关系数据库管理系统(RDBMS)所拥有的完善的功能,但是提供了一种可伸缩的键值存储。
SimpleDB is a simple data storage that lacks the sophistication of a full-fledged Relational Database Management System (RDBMS), while providing scalable key-value storage.
