Question- If a magnetic field strength of 4.7 T requires radio frequency of 200 MHz to achieve resonance with the nuclei (i.e. for the spin flips to occur), would a 300 MHz radio frequency NMR instrument need a magnetic field higher or lower than 4.7 T?
Please give an explanation so I know how to do future problems. Thanks!
