The main tendency of this paper is to bring an explanation of the relaxation times that are concur in Nuclear Magnetic Resonance (NMR). I remind primarily what is the NMR and spectroscopy. After that relaxation processes, which occur in NMR, are explained as well as their measurement....
The development of the technique of nuclear magnetic resonance proton imaging has led to an increased awareness of the changes in both content and characteristics of tissue water in normal and pathological conditions. This chapter discusses the NMR proton relaxation times in the study of the neonate...
A complex aging regime occurs in the course of thermal aging of elastomers. Depending on the type and the content of the rubber filler materials, temperature, chemical environment (normally air), and time, a different aging process can be observed also by nuclear magnetic resonance (NMR) [1鈥...

Structure and Dynamics in Amphiphilic Bilayers: NMR and MD simulation Studies The analysis of the order parameters measured is based on a combination of NMR experiments and MD simulations. With respect to the dynamics in bilayer systems, an NMR protocol for measurement of rotational diffusion is pre...

An X-ray and NMR study of structure and ion motions in C(NH2)3PF6 A single-crystal X-ray analysis has shown that guanidinium hexafluorophosphate C(NH2)3PF6 crystallises in the trigonal space group R3m, with a=7.427(3) AA,... M,Grottel,A,... - 《Journal of Physics Condensed Matter》...
NMR proton, deuteron and oxygen-17 relaxation rates were measured in different isotopic species of liquid ethanol and propanol and in their mixtures with carbon tetrachloride. For the pure alcohols a large temperature range could be covered and the relaxation rate maxima were obtained. Evaluation of...
