Well, I might have walked myself into a bit o' disaster. After long
deliberation with Gabe we decided that the singlet, doublet, triplet,
quartet designations on the carbon-13 NMR spectra are necessary to
determining exactly which carbon (as closely as can be approximated) in
the molecule corresponds to which peak. For example, in the molecule
there was one carbon (a singlet I think) that was part of a carbonyl
group-- we designated the two (the peak on the spectra and the carbon in
the molecule) with corresponding letters. Also there were two
singlet carbons involved in carbon-carbon double bonds so we assinged
letters to those carbons in the molecule that corresponded to the singlet
peaks in the alkene region of the spectra... Was this not what we were
supposed to do? Am we on base as to how to assign peaks to specific
carbons? Did anyone else try to interpret their spectra in this manner?
Also, I transfered the s, d, t, and q notations from the book (Pavia) to
the copy of the NMR spectra that I recieved from the stockroom window.
That's where I found the singlet, etc. notations. If you didn't interpret
your spectra like this, how'd you do it?
