The tube was continuously rotated round its axis to avoid temperature variations. Excitation of the magnet caused immediate widening of the lines. It thus appears very probable that the period of ...

interactions with external magnetic fields, and relaxation processes. The second portion of the course will discuss basic concepts of image formation, including radiofrequency pulse excitation, ...

Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...
