Nuclear spin-noise spectra of hyperpolarized systems.
Spin-noise appeal: Detection of NMR spin-noise is very appealing when dilute hyperpolarized species are considered. Continuous monitoring of the noise absorption at the Larmor frequency enables determination of T(1) and T(2)*, independently of the static magnetic field. An inductively coupled microcoil located inside the NMR tube (see picture) allows acquisition of (129)Xe spin-noise spectra without radio-frequency excitation.
