Nuclear Magnetic Resonance in Solid Zinc
نویسندگان
چکیده
The nuclear magnetic resonance of Zn in hexagonal close-packed Zn metal has been observed at 4.2 K by pulsed NMR with three different frequencies. The spin echo profile showed a well resolved powder pattern due to electric quadrupole interaction. The quadrupole coupling constant was determined to be e q Q/h = 12.0 (4) MHz. The spinspin and spin-lattice-relaxation times were measured to be T2 = 58 ± 2 ms and T1 = 0.45 ± 0.2 s, respectively. The isotropic Knight shift is found to have the value K\ s 0 = 0.1 ± 0.05%.

A 39-residue peptide (p7-DF) containing the two zinc binding domains of the p7 nucleocapsid protein was prepared by solid-phase peptide synthesis. The solution structure of the peptide was characterized using circular dichroic and nuclear magnetic resonance spectroscopy in both the presence and absence of zinc ions. Circular dichroic spectroscopy indicates that the peptide exhibits a random coi...
