Spin-lattice Relaxation of Reorienting or Tunneling Deuterated Methyl Groups
Tae spin-lattice relaxation of deuterated methyl groups, which is exponential at high temperatures, becomes non-exponential at low temperatures as evidence of the coupling between the Zeeman and tunneling systems. The dominant relaxation is considered to be the quadrupole interaction. Experimental results at liquid nitrogen and liquid helium temperatures support the theoretical model.
متن کاملCollision-induced tunneling in methyl halides
We use the technique of terahertz time-domain spectroscopy to investigate the absorption and dispersion of spectrally dense methyl halide vapors, particularly in the lowand high-frequency spectral wings. For the first time to our knowledge, it is possible to observe essentially zero-frequency absorption resulting from molecular tunneling between the two states of symmetry simultaneously, with a...
متن کاملSources of Betaine as Methyl Group Donors in Broiler Diets
Betaine is donor of methyl groups and can partially replace methionine in diets for this purpose. The objective of this study was to evaluate three sources of betaine in partial substitution of methionine supplement in broiler diets. The Cobb-500 broiler chickens were allocated in a completely randomized experimental design with 5 treatments and 7 replicates of 49 birds each. The positive contr...
متن کاملA Novel Initiator of [5-(benzyloxy)-4-oxo-4H-pyran-2-yl]methyl-2-bromo-2-methylpropanoateas in Atom Transfer Radical Polymerization of Styrene and Methyl Methacrylate
A novel nano-initiator containing kojic acid moiety, [5-(benzyloxy)-4-oxo-4H-pyran-2-yl)methyl-2-bromo-2-methylpropanoate was synthesized by the reaction of 5-(benzyloxy)-2-(hydroxymethyl)-4H-pyran-4-one with 2-bromoisobutyryl bromide in triethylamine and used as initiator in the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate in the presence of Cu(0)/CuCl2and N,N...
متن کاملAutomated sequence- and stereo-specific assignment of methyl-labeled proteins by paramagnetic relaxation and methyl-methyl nuclear Overhauser enhancement spectroscopy.
Methyl-transverse relaxation optimized spectroscopy is rapidly becoming the preferred NMR technique for probing structure and dynamics of very large proteins up to ~1 MDa in molecular size. Data interpretation, however, necessitates assignment of methyl groups which still presents a very challenging and time-consuming process. Here we demonstrate that, in combination with a known 3D structure, ...
