ABSTRACT:
Radiation damping effects in NMR are compensated by splitting the amplified NMR signal induced in the main probe coil to obtain a correction signal, phase shifting the correction signal to obtain a feedback signal and impressing the feedback signal onto the sample through means independent of the main probe coil.
