Web20 jul. 2015 · Abstract. Natural abundance 13 C NMR spectra of biological extracts are recorded in a single scan provided that the samples are hyperpolarized by dissolution dynamic nuclear polarization combined with cross polarization. Heteronuclear 2D correlation spectra of hyperpolarized breast cancer cell extracts can also be obtained in a single scan. Web3 feb. 2024 · This makes it possible to exploit the high spin polarization of optically polarized crystals, while mitigating the challenges of its transfer to external nuclei. With …

WebHyperpolarized 13C NMR spectra of propene, 1-butene, and isobutene are shown in Fig. 2. These spectra were measured at the natural abundance of 1% 13C. The originally generated hyperpolarization was distributed over multiple scans by applying a series of small ip angle pulses. A signal enhance-ment of several thousand-fold compared to non ... Web11 mei 2024 · To prepare the NMR spectrometer for the hyperpolarized water experiment, insert a standard reference sample (e.g., for a 5-mm o.d.
