The chemical shifts d (in ppm) and the structural formulae are given along with the complete references. The data are arranged according to the compounds. The arrangement of the compounds is based on their gross formulae according to the widely used Hill system. The complete data, the chemical shifts d (in ppm) and the coupling constants J (in Hz), including the structural formulae are available on the provided CD-ROM as PDF-files together with the program Adobe Acrobat Reader 3.0. You have to install only this program to jump directly into the data files and search for substances, references, chemical shifts, coupling constants and so on by the fulltext search engine.weiterlesen
