Atomic Line List

Atomic Line List是一个原子跃迁谱线数据库，收录了约923,000条允许的、组合禁戒和禁戒的原子跃迁数据，波长范围从0.5埃到1000微米。该数据库主要用于识别观测到的原子吸收或发射特征，波长数据均通过上下能级能量差计算得出，而非观测值。数据库主要数据来源于美国国家标准与技术研究院(NIST)的原子光谱数据库。Atomic Line List is an atomic transition spectral line database that contains approximately 923,000 entries of allowed, intercombination and forbidden atomic transition data, with a wavelength range from 0.5 Å to 1000 μm. This database is primarily used for identifying observed atomic absorption or emission features. All wavelength data are calculated based on the energy differences between upper and lower energy levels, rather than being directly measured values. The primary data source of this database is the Atomic Spectroscopy Database of the National Institute of Standards and Technology (NIST).
