ABSTRACT:
A dual frequency NMR coil pair is comprised of two individual coils tuned to separate resonant frequencies. Each coil is formed into approximately the same shape by a conductive loop which follows a serpentine path to define an inner area and a plurality of outer lobes. The two individual coils are positioned in close proximity overlying each other, but rotated with respect to each other such that the outer lobes of the two respective coils are interleaved, i.e. not overlaying each other. As a result, mutual loading between the two individual coils is essentially eliminated, permitting dual frequency operation with minimal degradation of Q or signal-to-noise ratio (SNR) in either coil.
