WebVideo transcript. We've already looked at a carbon-hydrogen bond, and in the last video, we actually calculated an approximate wavenumber for where we would expect the signal for a carbon-hydrogen bond stretch to appear on our IR spectrum. And we got a value of a little bit over 3000 wavenumbers. WebC-NMR spectra basics. Interpreting C-NMR. DEPT C-NMR. 2D-NMR. Since a nucleus is a charged particle in motion, it will develop a magnetic field. 1 H and 13 C have nuclear spins of 1/2 and so they behave in a similar fashion to a simple, tiny bar magnet. In the absence of a magnetic field, these are randomly oriented but when a field is applied ...
