Unformatted text preview: evolution. b) Calculate the phase evolution of each component (a, b, and c) after time τ , just before the 180º pulse. Now, calculate the phase difference picked up by components a versus b and a versus c. Also, d raw the effects on a separate vector diagram. c) Repeat part (b) for the time immediately following the 180º pulse. d) Repeat part (b) for the time where the echo amplitude is maximal. You can either use absolute phase or phase differences picked up by the three frequency components. It may be easier to put your arguments forward by using phase differences. Illustrate the results by means of vector diagrams....
