NMR & IR Spectroscopy Problem Set Read the notes and Chapter 15 in the Klein lecture text which is devoted to NMR spectroscopy. This information will give you an overview, specifics will be discussed in the lectures devoted to 'Hand C NMR. Review the "index of hydrogen deficiency" (IHD) which is also known as "degree of unsaturation calculations. Predict the 'H and "C NMR Spectra for the following structures For each structure, determine the number of unique sets of protons or carbons, as this corresponds to the number of signals in each NMR spectrum. Predict the approximate chemical shift values for each signal (in ppm) for the "C NMR spectra. Predict the chemical shift values for each signal in the 'H spectra. Also give the integration values and signal splitting for the 'H NMR. 6 o 7 Br CHE H 8 нсо OCH OH 9 7 10 H2CO H3C H 5 CI CHCI
