An electro-mechano-optical NMR probe for H-C double resonance in a superconducting magnet.

Electro-mechano-optical (EMO) NMR, an emerging NMR detection technique with signal upconversion from radiofrequency to optical regimes a SiN nanomembrane, has become compatible with NMR analysis in chemistry using a highly homogeneous but space-limited magnetic field provided by a superconducting magnet (SCM) by development of a compact EMO NMR probe operational inside the SCM bore. Optical C NMR signal detection following H-C magnetization transfer in liquid benzene is demonstrated.
