Zero-dead Time NMR in Low Field: Single-Sideband Technique Revisited

Abstract

Recently the rapid-scan technique is reviving in NMR or EPR, because of its benefits of zero-dead time and low RF power. While signal baseline is still a big problem in such experiments, time-share method has been used to indirectly avoid it. However, it is obviously not a truly zero-dead time method. Other data-processing methods were also adopted to deal with raw data. Here we try to use single-sideband technique at 11.4MHz to mitigate this obstacle. The prospect is that single sideband technique can be used in rapid-scan experiment for low/high field imaging.
