吸收光谱和荧光光谱对于整个光科学来说是必不可少的，但这些光谱以及摩尔吸收系数 (ε) 和荧光量子产率 (Φf) 的所有重要值通常很难找到。在此，一项关于重要叶绿素化合物类别的文献调查已确定了 150 名成员的光谱。印刷形式的光谱已被数字化（带有基线校正）并与参考文献、溶剂标识和 ε 和 Φf 值（如果可用）一起组装到数据库中。该数据库包括光合四吡咯，其中生色团是卟啉（例如叶绿素c1、原叶绿素a）、二氢卟酚（例如叶绿素a、细菌叶绿素c）或细菌绿素（例如细菌叶绿素a）。共，该数据库包含 305 个吸收光谱（来自 19 个卟啉、109 个二氢卟酚和 22 个菌绿素）和 72 个荧光光谱（来自 10 个卟啉、30 个二氢卟酚和 4 个菌绿素）。光谱数据库应便于比较和定量计算。所有光谱都以印刷形式在支持信息中提供。PhotochemCAD 程序提供了数字形式的整个数据库，可在 http://www.photochemcad.com 上免费下载和进一步使用。

Absorption and Fluorescence Spectral Database of Chlorophylls and Analogues

Absorption spectra and fluorescence spectra are essential for use across the photosciences, yet such spectra along with the all‐important values for molar absorption coefficient (ε) and fluorescence quantum yield (Φf) often are found with great difficulty. Here, a literature survey concerning the vital class of chlorophyll compounds has led to identification of spectra for 150 members. Spectra in print form have been digitized (with baseline corrections) and assembled into a database along with literature references, solvent identity and values for ε and Φf (where available). The database encompasses photosynthetic tetrapyrroles wherein the chromophore is a porphyrin (e.g. chlorophyll c1, protochlorophyll a), chlorin (e.g. chlorophyll a, bacteriochlorophyll c) or bacteriochlorin (e.g. bacteriochlorophyll a). Altogether, the database contains 305 absorption spectra (from 19 porphyrins, 109 chlorins and 22 bacteriochlorins) and 72 fluorescence spectra (from 10 porphyrins, 30 chlorins and 4 bacteriochlorins). The spectral database should facilitate comparisons and quantitative calculations. All spectra are available in print form in the Supporting Information. The entire database in digital form is available with the PhotochemCAD program for free downloading and further use at http://www.photochemcad.com.
