资源简介：
NIST Chemistry WebBook是美国国家标准与技术研究院(NIST)维护的标准参考数据库第69号(SRD 69)，提供化学物质的 thermochemical、thermophysical 和离子能量学数据。该数据库包含大量化合物的物理性质、热力学性质、光谱数据等信息，可通过化学名称、分子式、CAS号等多种方式检索。数据来源经过严格验证，广泛应用于化学、物理、工程等领域的科学研究。
The NIST Chemistry WebBook, designated as Standard Reference Database 69 (SRD 69), is maintained by the National Institute of Standards and Technology (NIST). It provides thermochemical, thermophysical, and ion energetics data for chemical substances. This database contains extensive information such as physical properties, thermodynamic properties and spectral data for a large number of compounds, and supports retrieval via multiple methods including chemical names, molecular formulas and CAS registry numbers. The data sources have undergone rigorous validation, and the database is widely applied to scientific research in fields such as chemistry, physics and engineering.
