DBE and HNMR Spectroscopy

When I took orgo 1 and 2, a chemical formula (such as C3H6O4) would be given along with the HNMR spectra. We would then have to calculate the double bond equivalency (DBE), and determine the structure.

How in-depth is HNMR on the DAT? Do we need to calculate DBE to solve the problems?

Pretty simple and basic, and I've never been aware the need of using DBE to solve an NMR problem. The trickier part of the DAT on this probably lies with your ability to recognize superposition of peaks on similar points along the spectra, especially when dealing with structure having a symmetry plane/line.

Cool, thanks for the heads up.
