Chemical shift in H-NMR

  1. Apr 4, 2017 #1
    1. The problem statement, all variables and given/known data
    I'm trying to interpret an H-NMR of NiCl2 (dppe) and am trying to match the peaks in the aromatic region.

    2. Relevant equations

    3. The attempt at a solution
    http://[URL=http://s350.photobucket.com/user/remerril/media/hnmr_zpseljx6e8x.png.html][ATTACH=full]200208[/ATTACH] I think that the hydrogens at positions A and A' prime are the peak with an integration of 1 and the hydrogens at B, B', and C are the peak with an integration of 1.5280. since the hydrogens at D and D' are causing the 0.4992 peak, the numbers of hydrogens match up. If this is true, why are the hydrogens at A and A' at a higher chemical shift than the others?

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
