This thesis describes a quadruple-resonance 1H/13C/2H/15N magic-angle spinning nuclear magnetic resonance probe for the study of structure and dynamics of biological macro- molecules. The probe utilizes tuning-tube components as discrete circuit elements. A coaxial design allows specialization, with the high-frequency 1H circuit on a low-voltage modified Alderman-Grant coil and the 13C/2H/15N circuit on a solenoid coil for more efficient detection. The mechanical and circuit design of the probe is presented with a description of the benchtop characterization and some initial experimental results.
