Abstract:The first observation of the resolved Mims electron-nuclear double resonance (ENDOR) spectra from the nearby and remote nuclei of 19F and 7Li nuclei on impurity Ce3+ ions in LiYF4 crystal is reported. It shows that LiYF4:Ce3+ system can be exploited as a convenient matrix for performing spin manipulations and adjusting quantum computation protocols while ENDOR technique could be used for the investigation of electron-nuclear interaction with all the nuclei of the system and exploited for the electron-nuclear spin manipulations.

Abstract:In the present paper the applicability of a structure determination for a four amino acid residues containing oligopeptide N-Ac-Ser-Phe-Val-Gly-OMe was investigated. The spatial structure of the "tetrapeptide (N-Ac-Ser-Phe-Val-Gly-OMe) - sodium dodecyl sulfate micelle" complex in aqueous solution was studied by 2D nuclear magnetic resonance (NMR) spectroscopy. The complexation was confirmed NOEs signs and values in the presence of sodium dodecyl sulfate. The spatial structure of the tetrapeptide in the complex was determined by 2D NOESY NMR spectroscopy. In present paper by the comparison 13C NMR chemical shifts was shown that tetra peptide's spatial structure in solid state and tetrapeptide structure in "peptide-micelle" complex are identical.

Subject Terms:*NUCLEAR magnetic resonance spectroscopy, *QUADRATURE domains, *DIGITAL technology, *RADIATION, *POTENTIAL theory (Mathematics)

Abstract:The home-built pulse nuclear magnetic resonance spectrometer for 3He research is described. The temperature range is 1.5 - 4.2 K, the frequency range is 3 - 20 MHz, the dead time is 10 μs at 10 MHz. The spectrometer software is based on programming language LabVIEW. The advantages of digital technique are described; particularly the implementation of digital quadrature detector. [ABSTRACT FROM AUTHOR]
