Experimental realization of quantum information processing in the field of nuclear magnetic resonance (NMR) has been well established. Implementation of conditional phase-shift gate has been a significant step, which has lead to realization of important algorithms such as Grover's search algorithm and quantum Fourier transform. This gate has so far been implemented in NMR by using coupling evol...

We present nuclear spin-rotation constants, absolute nuclear magnetic resonance (NMR) shielding constants, and shielding spans of all the nuclei in (175)LuX and (197)AuX (X = (19)F, (35)Cl, (79)Br, (127)I), calculated using coupled-cluster singles-and-doubles with a perturbative triples (CCSD(T)) correction theory, four-component relativistic density functional theory (relativistic DFT), and no...

1, 4-Diazabicyclo [2.2.2] octane (DABCO) was employed as a catalyst for one-pot synthesis of pyrano[2,3-d] pyrimidinone derivatives and MWNT- pyrimidinones from condensation reactions of aromatic aldehydes, malononitrile and thiobarbituric acid and MWNT-COCl . This method delivers the advantages of a simple method, environment friendly procedure, mild reaction conditions and high returns. The m...

A Theory of Nuclear Magnetic Resonance (NMR) is developed for integerspin, one-dimensional antiferromagnets, which exhibit the Haldane gap. We consider free boson, free fermion and non-linear σ-model approaches, all of which give similar results. Detailed anisotropy and magnetic field dependence is calculated and compared with experiment. 75.10 Jm Typeset using REVTEX 1

the factors such as disease can disrupt homeostasis, resulting in perturbations of endogenous biochemicals that are involved in key metabolic profiles. metabonomics is useful technique to quantitative description of endogenous metabolites present in a biological sample such as urine, plasma and tissue. high resolution 1 h nuclear magnetic resonance (nmr)-based metabonomics is a technique used t...
