    NMR NOESY spectrum -- Please help! "trans-9-(2-phenylethenyl) anthracene"

    Here is the NOESY spectrum:

    Here is the Proton NMR and the structure of the molecule:

    trans-9-(2-phenylethenyl) anthracene

    I need to label this NOESY and see which hydrogens are interacting with each other.
    But with so many peaks all clustered together at the benzene area ... I can't tell them apart!

    Also, I may have numbered my carbons wrong.

    Please help me out!

    FYI
    Here is my attempt...
    I'm sure it's incorrect :)

    Did you obtain this spectrum yourself? Why would you label the two resonances at 1.4ppm and 1.6ppm as your two vinyl groups? Where do vinyl groups usually show up?

    What did you use as an internal standard?
