Re: I need some help interpreting these NMR and IR spectra. (Identify Unknowns lab) «Reply #2 on:April 14, 2018, 01:09:56 AM » here is a good resource for some interactive practice problems with posted solutionshttp://www-usr.rider.edu/~grushow/nmr/NMR_tutor/selftests/problems_...
In addition to questions solely focused on proton NMR, some textbooks feature combinations of questions that require students to extract information from various other spectra such as IR, 13C NMR, 2D-NMR and Mass Spectrometry. However, authors have observed that the problems in the textbooks may ...
I have a feeling that the spectrscopy problems in my course are a little on the tougher end. They typically involve NMR (usually 1H, 13C, or both), IR, as well as some clues about the molecule's reactivity. E.g. in this question, we are given the hint that a polymer was reacted...
In Section 9, the effect of spatial encoding and spatial selection on sensitivity is analysed. Finally, Section 10 presents a selection of applications of spatial encoding and spatial selection methods, including solutions to problems that would otherwise remain out of the reach of NMR spectroscopy....
Future studies are also expected to repeat the method on more metabolite data and larger data sets to further verify its reliability. In summary, this study provides a comparison of the complete flow of the two experiments and suggestions for countermeasures to possible problems currently encountered...
However, in practice, both symmetry and mobilitymay vary widely, thus introducing variations that may amount to several powers of ten.Table 1 gives the data for the spin-1–2nuclei in the periodic table, whereas Table 2 refers toquadrupolar nuclei. These two tables omit the lanthanide and ...

NMR serves as an important technique for probing rock pore space, such as pore structure characterization, fluid identification, and petrophysical property testing, due to the reusability of cores, convenience in sample processing, and time efficiency in laboratory tests. In practice, NMR signal collec...
