Many nmr solvent peak lists are very useful but not complete. Ⅰ usually just refer to the [J.Org.Chem article by Gottlieb et al.](http://dx.doi.org/10.1021/jo971176v
„link to Article’s DOI“) for solvent peaks, the corresponding chemical shifts for water and other commonly used solvents) – but DMF is not on that list as a solvent. A quick googling returned this list:NMR-Lösungsmittel. The introductory text is in German, and translates as:
br = broad signal, ⅿ = fine structure of peaks
*water peaks* depending on concentration and polarity of the dissolved compounds the water peaks may be shifted a bit; temperature differences also influence the chemical shift of water. All 1H-spectra show a broad water peak as a result of atmospheric humidity – usually this peak is neglectable, but in very dilute solutions your integrals may be affected
[this is the Google search](http://www.google.com/search?client=safari&rls=de-de&q=nmr+solvent+dmf&ie=UTF-8&oe=UTF-8), resulting in [another good table](http://chemlab.truman.edu/Miscellaneous_files/NMRSolvents.htm), [another one](http://www.acornnmr.com/solvents.htm), and many more 
Ⅰ student of mine just told me about iNMR… and since Ⅰ like looking at α software (the version is supposed to be 0.0) Ⅰ gave it a shot.
1. First impression: horrible. No toolbar, nothing mac like, as far as Ⅰ am concerned. A look into the menu bar revealed some functions, but somehow Ⅰ was missing the functionalities of Win-NMR or XWin-NMR (which, of course is a) not a nice thing to do, comparing a newcomer to the old bastards and b) which is in itself unfair again, as both apps are not on OSX and have horrible interfaces.) But then Ⅰ gave it a try…
2. Second impression: well there are many functions available, Ⅰ accidentally started hitting keys on my keyboard and suddenly Ⅰ could do all sorts of things: integration, zooming, marking…
3. Third impression: the web based documentation is superb. The graphics are nice.. (and you can also take screenshots)
*Summary:*
This little app is very promising. It is ba far the best NMR app Ⅰ have seen on OSX so far, and this is just a very early pre-release. Although ⅰ am not very happy with a) the interface and b) the pricing (yes, it is very early and pre-release — Ⅰ can also understand why the makers are doing it, doesnt mean Ⅰ need to be happy with it!).
Ⅰ will give it a look later on – and Ⅰ might end up buying a license for myself – just to make pretty pictures for my thesis…
