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. 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, resulting in another good table, another one, 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.
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…
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…
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…
The NMR processing software RMN is now available as an alpha version for MacOSX.
