Purpose Magnetic resonance T1-weighted images are routinely used for human brain segmentation, brain parcellation, and clinical diagnosis of demyelinating diseases. Myelin is thought to influence the longitudinal relaxation commonly described by a mo

Chemical shifts δ have been calculated for the 1 H attached to carbon atoms of sarcosine. Eight levels of theory within the DFT approach were used, mixing the four functionals B3LYP, PBE, OPBE, PBE0 and the two basis sets 6-311++G∗∗ and pcJ2. Bo

This paper reports for the first time both, an experimental observation and theoretical calculations of the K 2 4 3 Δ g state. For the experiment we used cw perturbation-facilitated optical–optical double resonance (PFOODR) spectroscopy. A single
