The spectroscopy of diatomic molecules is an important research area in chemical physics due to its relevance in astrochemistry, combustion chemistry, and ultracold physics. However, there is currently no database where the user can easily retrieve, in a useful format, the spectroscopic constants of a given molecule. A similar situation appears concerning the vibrational Franck-Condon factors for diatomic molecules, a crucial parameter to infer laser cooling prospects for molecules. To address this problem, and inspired by the idea that data should be open and freely accessible, we have developed a user-friendly website (https://rios.mp.fhi.mpg.de) where the user can retrieve spectroscopic constants and Franck-Condon factors in useful formats.
In this database, the spectroscopic constants of the ground states and first excited states of the diatomic molecules are accessible from the website and can be retrieved in readable formats. The website is implemented within the LAMP web service stacks. In particular, using Linux as the operative system, Apache as the HTTP Server, MySQL as the database management system, and PHP as the programming language for the web. Furthermore, the user can register and upload new data. This project is licensed under the Free-Libre/Open Source Software (FLOSS) license Apache License 2.0 which allows free and open access to the codes as well as efficient collaboration in the maintenance of the software.
The present data-driven website presents essential information in a user-friendly manner and may help the chemical physics community to identify molecules that should be explored through spectroscopic techniques.
双原子分子光谱学是化学物理领域的一个重要研究方向,因为它在天体化学、燃烧化学和超冷物理中都具有重要意义。然而,目前尚无一个数据库能让用户以实用格式轻松检索给定分子的光谱常数。对于双原子分子的振动弗兰克 - 康登因子这一推断分子激光冷却前景的关键参数,情况同样如此。为解决这一问题,并受数据应开放且可自由获取这一理念的启发,我们开发了一个用户友好型网站(https://rios.mp.fhi.mpg.de),用户可在此以实用格式检索光谱常数和弗兰克 - 康登因子。
在这个数据库中,双原子分子基态和第一激发态的光谱常数可从网站获取,并能以可读格式检索。该网站是在LAMP网络服务栈中实现的。具体而言,使用Linux作为操作系统,Apache作为HTTP服务器,MySQL作为数据库管理系统,PHP作为网站编程语言。此外,用户可以注册并上传新数据。该项目遵循自由/libre/开源软件(FLOSS)许可协议Apache License 2.0,允许自由开放地访问代码,并能在软件维护方面进行高效协作。
这个以数据驱动的网站以用户友好的方式呈现重要信息,可能有助于化学物理领域的研究人员识别那些值得通过光谱技术进行探索的分子。
