Abstract: Under normal physiological conditions, the spin–lattice relaxation rate (R1) in blood is influenced by many factors, including hematocrit, field strength, and the paramagnetic effects of deoxyhemoglobin and dissolved oxygen. In addition, techniques such as oxygen‐enhanced… read more here.

DOI: 10.1039/d2cp03458a
Abstract: Spin–lattice relaxation rate (R1) measurements are commonly used to characterize protein dynamics. However, the time needed to collect the data can be quite long due to long relaxation times of the low-gamma nuclei, especially in… read more here.
