Nuclear Magnetic Resonance Project

The magnetic moment of a nucleon is sometimes expressed in terms of its g-factor (a dimensionless scalar) as , where is an intrinsic magnetic moment, is the nuclear magneton and is given by , is the nucleon's g-factor, is the nucleon's spin angular momentum number and is the nucleon's mass. The Hydrogen/Proton Gyromagnetic Ratio, , is equal to .

The proton's g-factor


So,

Our magnet will produce fields up to ~ 0.7T. This allows for transverse field frequencies up to ~ 30MHz. We employ a bridged-Tee detector (Waring - 1952) to observe the NMR signal.
