>>7640966 The molecule is more or less flat: 2D NMR won't help whatsoever.
>>7640996 Here are some helpful questions to ask yourself to figure out what your 13C should look like: 1. How many signals do you expect to see? 2. Which signal(s) do you expect to be most diagnostic? 3. Do you see something close to those diagnostic signals? 4. (If you're really worried) does the 13C APT demonstrate the correct number of methyl/methyne and methylene/quat carbons?
>>7641859 >The molecule is more or less flat: 2D NMR won't help whatsoever. What. I mean, maybe 2D NMR won't help much in his case. But it's got nothing to do with his molecule being flat. HMQC, HMBC, COSY, NOESY could all help in assigning proton signals to 13C signals. (NOESY probably won't be necessary.)
