for the 90 degreepulse. The quality factor of the coil must be high enough in order to achieve areasonable SNR. The quality factor is ωL 2πf L Q= = (2) R RIt is therefore important to keep the inductance L high enough. n2 a2 L= (3) 23a + 25bwhere a is the coil diameter (cm), b the length (cm) and n the number of turns.The coil used in this system is a two-layer 60 turn coil which tightly encloses thesample volume in order to minimize
