AI Article Synopsis
- The text discusses a novel two-dimensional NMR spectroscopy method that detects noise from nuclei not exposed to radio frequency excitation.
- This technique uses cross-correlation of noise blocks during specific time periods to gather data.
- Despite lower sensitivity in traditional setups, this spin-noise-detected approach shows promise for studying tiny samples, enabling nanoscale multidimensional NMR spectroscopy.
Article Abstract
We introduce two-dimensional NMR spectroscopy detected by recording and processing the noise originating from nuclei that have not been subjected to any radio frequency excitation. The method relies on cross-correlation of two noise blocks that bracket the evolution and mixing periods. While the sensitivity of the experiment is low in conventional NMR setups, spin-noise-detected NMR spectroscopy has great potential for use with extremely small numbers of spins, thereby opening a way to nanoscale multidimensional NMR spectroscopy.
