| Ultra-Low and Truly Zero-Field Nuclear Magnetic Resonance |
| Speaker: | Piotr Put (Jagiellonian University) |
| Abstract: | While the general direction in nuclear magnetic resonance (NMR) technique is to move towards ever stronger magnetic fields, resulting in better signal, resolution and chemical specificity, the opposite tendency of performing NMR experiments in ultra-low magnetic fields has also emerged in recent years. In contrast to conventional high-field NMR, where the coupling with the external magnetic field is the dominant interaction, the nuclear spin evolution in this field regime is governed predominantly by the spin-spin (J) coupling. As the need for strong (T- regime) magnetic fields is alleviated, we can take advantage of a number of practical advantages- large decrease in size and price of such spectrometer devices or of unique measuring opportunities (e.g., samples in metallic enclosures, inhomogeneous mixtures etc.). During my seminar I will explain how to obtain nonequilibrium spin polari |
