我们介绍了分子振动浏览器,这是一个免费访问的在线数据库和交互工具,用于探索大量硫代化分子的振动光谱和张量光-振动耦合强度。该数据库的“Gold”版本收集了2800种与金原子相连的商用硫醇化合物的密度泛函理论计算结果,主要目的是筛选出太赫兹和中红外到可见光上转换的最佳分子。此外,数据库的“硫醇”版本包含1900个未结合的硫醇化合物的结果。它们都提供了对数据库中所有分子所有振动模式的一套全面的计算光谱参数的访问。用户可以同时研究红外吸收、拉曼散射和振动和差频产生截面。可以在定制的频率范围内筛选分子的各种参数,例如特定分子取向下的大拉曼截面,或大取向平均和频产生(SFG)效率。用户可以选择电磁场的偏振矢量,设置分子的取向,并定制绘制相应的IR、拉曼和和频谱的参数。我们通过在表面增强光谱领域中的选定应用来说明该工具的能力。
We present Molecular Vibration Explorer, a freely accessible online database and interactive tool for exploring vibrational spectra and tensorial light-vibration coupling strengths of a large collection of thiolated molecules. The “Gold” version of the database gathers the results from density functional theory calculations on 2800 commercially available thiol compounds linked to a gold atom, with the main motivation to screen the best molecules for THz and mid-infrared to visible upconversion. Additionally, the “Thiol” version of the database contains results for 1900 unbound thiolated compounds. They both provide access to a comprehensive set of computed spectroscopic parameters for all vibrational modes of all molecules in the database. The user can simultaneously investigate infrared absorption, Raman scattering, and vibrational sum- and difference-frequency generation cross sections. Molecules can be screened for various parameters in custom frequency ranges, such as a large Raman cross-section under a specific molecular orientation, or a large orientation-averaged sum-frequency generation (SFG) efficiency. The user can select polarization vectors for the electromagnetic fields, set the orientation of the molecule, and customize parameters for plotting the corresponding IR, Raman, and sum-frequency spectra. We illustrate the capabilities of this tool with selected applications in the field of surface-enhanced spectroscopy.
