This website provides resources that can aid in the assigning NMR proton shifts, IR peaks and mass loss in mass spectrometry. The original site is in German, but most (but not all) the content is translated on the English version of the site. From the left hand menu under Spektroskopei-Tools choose Wizards. From here you can…
This web site provides thirty beginning, twenty-nine intermediate, and sixteen advanced NMR structure analysis problems and their solutions. For every unknown a proton and a carbon spectrum are provided. Many of the more advanced problems contain COSY and DEPT spectra as well. A particularly useful feature of this site is that the user can zoom into…
This web site contains 64 structure elucidation problems for the qualitative analysis of organic compounds. For each problem the empirical formula, molecular weight, 500 MHz proton and 125 MHz carbon NMR spectra, IR and mass spectral data are presented. The problems are categorized as easy, moderate or difficult. Students in introductory Organic Chemistry who want practice…
