MDL CrossFire Commander

All chemical shift data presented in this book come either from the primary literature or from spectra obtained in the author s laboratory. All spectra actually depicted in the book derive from spectra obtained by the author at the University of Florida. All data from the literature were obtained via searches using MDL Crossfire Commander or SciFinder Scholar. Persons interested in accessing such primary literature can do so readily via these databases by simply searching for the specific compound mentioned in the text. 

Regarding the multitude of NMR chemical shifts of specific compounds that are provided within the text, references for chemical shifts of individual compounds for the most part will not be cited. It is assumed that if such references are required, the reader can find them by a quick search using either MDL Crossfire Commander or SciFinder Scholar. The author found MDL Crossfire Commander the superior database for locating specific NMR data. 

References to data retrieved from a stand-alone database should cite the source as a computer program (for example, MDL CrossFire Commander, see p 323 f) or as an online reference book (for example, the Kirk-Othmer Encyclopedia of Chemical Technology, see p 305 f), with the data entry number or other identifying information included at the end of the citation. Data retrieved from an Internet-based database should cite the source as a Web site (see pp 316 ff). If the data retrieved are calculated data, also cite the software used for calculation (for example, ACD/Labs). 

Beilstein is a much more comprehensive database, marketed under the name of MDL Crossfire, and requires a subscription fee for access. It contains far more organic substances and lists many more properties. The search commands include ...
