explain your answers. 8. (2 points) Calculate the ratio of the absorption energy (e.g., for a bare proton) to
its thermal kinetic energy (say, at 20° C)? Why does this ratio make NMR
absorptions relatively weak, compared to UV, visible, or IR spectroscopy? LS5501 Biophysical Principles
Dr. Laity, Fall 2012 9. (1 points) Assuming a magnetic field B0 along the z axis and a 90o (π/2) RF pulse
(B1) along the +x axis, which axis would you expect to find the bulk nuclear
magnetization (M) immediately after the pulse has finished (assuming M was
initially along the z-axis; see figure below): B0
10. (2 points) Calculate the Larmor frequencies and transition energies for a
unshielded 1H, 13C, and 15N nuclei at 600 MHz....
