Key Points

  • The research aims to understand how generalized level anticrossings affect hyperpolarisation in the SABRE technique under oscillating magnetic fields.
  • Investigation of SABRE using oscillating magnetic fields
  • Analysis of polarisation transfer mechanisms
  • Quantitative assessment of NMR signal enhancements
  • Improved hyperpolarisation observed under oscillating magnetic fields
  • Enhanced NMR signal strength compared to conventional SABRE
  • Findings support the role of level anticrossings in signal amplification

Abstract

Signal amplification by reversible exchange (SABRE) is a parahydrogen-based hyperpolarisation technique that significantly enhances nuclear magnetic resonance signals without expensive hardware. While conventional SABRE relies on a static polarisation transfer...
