The objective of this exercise is to demonstrate an understanding of the principles on which HNMR spectroscopy is based, and to use these principles to elucidate the structural formulas of simple organic compounds. 1. Both 'H and 19F have a spin quantum number of 172. Based on this information, determine the number of possible spin states for 19F in an external magnetic field. 2. The HNMR spectrum below has three different signals. What information is obtained from the number of signals (3 in this case) in an HNMR spectrum? PPM 3. The three signals in the above spectrum appear at different locations along the spectrum. What determines the signal position (chemical shift) of each signal? 4. What information is obtained from the intensity or peak area of the signals in the above spectrum
