Abstract
Relaxation and diffusion NMR (Laplace NMR) experiments provide versatile information about the dynamics and structure of substances. Like in traditional NMR spectroscopy, the resolution and information content of LNMR can be significantly increased by the multidimensional approach. However, long experiment time restricts the applicability of the multidimensional methods. As a solution for this problem, we are developing a broad range of ultrafast, single-scan multidimensional LNMR experiments, based on the principles of continuous spatial encoding that have been successfully applied in ultrafast multidimensional NMR spectroscopy. The method shortens the experimental time by one to three orders of magnitude as compared to the conventional method. Furthermore, it facilitates significantly the use of hyperpolarized substances to boost the sensitivity by several orders of magnitude. The method has many interesting applications in various disciplines. It is also feasible with low field, single-sided instruments, which are portable and much cheaper than the high-field spectrometers.
