手性藥物數(shù)據(jù)庫(免費(fèi))
    六百多種商用手性藥物，涵蓋了528種全合成手性藥物的大部分和一部分半合成手性藥物，其中已拆分的藥物四百多種。數(shù)據(jù)庫提供了詳細(xì)的拆分方法和拆分條件,并配以結(jié)構(gòu)式、分子式、分子量、結(jié)構(gòu)譜圖及藥物主要作用，以及盡可能多的其它藥物信息，可為藥物手性分析研究及手性藥品檢測提供頗具價值的參考依據(jù)。

Atomic Line List (原子吸收、發(fā)射性能數(shù)據(jù))(免費(fèi))
This is a compilation of approximately 923,000 allowed, intercombination and forbidden atomic transitions with wavelengths in the range from 0.5 ? to 1000 μm. Its primary intention is to allow the identification of observed atomic absorption or emission features. The wavelengths in this list are all calculated from the difference between the energy of the upper and lower level of the transition. No attempt has been made to include observed wavelengths. Most of the atomic energy level data have been taken from the Atomic Spectra Database provided by the National Institute of Standards and Technology (NIST).
