Abstract

Sensitivity enhancement by the use of inductively coupled milli‐ and microcoils has been demonstrated in solid‐state as well as liquid‐state NMR. In this work, we discuss the practical aspects of using inductively coupled solenoid coils of different sizes in a liquid‐state NMR spectrometer. The sensitivity and resolution enhancements from these resonant coils, with sizes ranging between 3.0 and 0.75 mm i.d., are measured for ^23^Na single‐pulse and multidimensional imaging experiments and compared to the results obtained with the conventional liquids NMR 5.0‐mm saddle coil. Enhancements in voxel‐based sensitivity (SNR per √scans) were measured in multidimensional MR images and were found to be as large as 20.4 with the 0.75‐mm coil.
