NIST Chemistry WebBook - SRD 69

The NIST Chemistry WebBook provides users with easy access to chemical and physical property data for chemical species through the internet. The data provided in the site are from collections maintained by the NIST Standard Reference Data Program and outside contributors. Data in the WebBook system are organized by chemical species. The WebBook system allows users to search for chemical species by various means. Once the desired species has been identified, the system will display data for the species. Data include thermochemical properties of species and reactions, thermophysical properties of species, and optical, electronic and mass spectra.

美国国家标准与技术研究院化学网络书籍为用户提供便捷的途径，通过互联网获取化学物种的化学和物理性质数据。网站提供的数据源自美国国家标准与技术研究院标准参考数据计划维护的集合以及外部贡献者的贡献。网络书籍系统中的数据按照化学物种进行组织。该系统允许用户通过多种方式搜索化学物种。一旦识别出所需的物种，系统将显示该物种的数据。数据包括物种及其反应的热化学性质、物种的热物理性质，以及光学、电子和质谱数据。
