Thermal Convection Currents in NMR: Flow Profiles and Implications for Coherence Pathway Selection

Research output: Contribution to journalArticlepeer-review

Abstract

Rayleigh-Bénard convection currents are visualized in a vertical cylindrical tube by means of magnetic resonance imaging. Axially antisymmetric flow, multiple vertical rolls, and twisted node planes are observed. The flow can also be induced by strong RF irradiation. Its effects on the coherence pathways in NMR experiments employing field gradients are discussed.
