I saw your response, but did not view it as responding to the vast differences in the NMR's that Randy was pointing out. So no I did not miss your comment.Nope, I responded to that. You just somehow missed my comment. Once again, I'd like to remind you that the spectra presented here are from unknown mixtures. Mixtures. Not pure compound like the reference spectrum supplied by Randy. Mixtures. Which, again, is what I have repeatedly asked about.
