(a) What does "600 MHz" refer to when discussing NMR instrumentation? (b) Calculate the magnetic field strength (in Tesla) of the 600 MHz NMR instrument. (c) Calculate the resonant frequency of a ¹3C nucleus for the 600 MHz NMR. (d) Identify the two coolants used in an NMR instrument and describe their purpose. (e) Circle the NMR active nuclei: 150, 12C, 15N, 30P, 2H Identify and briefly describe the two types of NMR relaxation processes. (g) Determine the totall number of expected 'H NMR peaks, the splitting for each peak, and the relative peak intensity ratios for CH₂CH₂OCH, (drawing out the molecule will help!)
