  • clean absorption mode nmr data acquisition based on time proportional Phase Incrementation
    Journal of Structural and Functional Genomics, 2009
    Co-Authors: Arindam Ghosh, Thomas Szyperski
    Abstract:

    Clean absorption mode NMR data acquisition is presented based on mirrored time domain sampling and widely used Time-Proportional Phase Incrementation (TPPI) for quadrature detection. The resulting NMR spectra are devoid of dispersive frequency domain peak components. Those peak components exacerbate peak identification and shift peak maxima, and thus impede automated spectral analysis. The new approach is also of unique value for obtaining clean absorption mode reduced-dimensionality projection NMR spectra, which can rapidly provide high-dimensional spectral information for high-throughput NMR structure determination.

  • radio frequency driven electron spin echo envelope modulation spectroscopy on spin systems with isotropic hyperfine interactions
    Journal of Chemical Physics, 2001
    Co-Authors: M Kalin, A Schweiger
    Abstract:

    Three-pulse radio-frequency (rf) driven electron spin echo envelope modulation (ESEEM) is introduced as a method to measure hyperfine couplings of electron–nuclear spin systems in liquids. It is distinguished from the corresponding two-pulse experiment by narrower lines. Numerical simulations of rf-driven ESEEM based on Floquet theory are given and compared with average Hamiltonian theory. Artifacts which appear in rf-driven ESEEM spectra are discussed, and approaches for the removal of these artifacts such as Time-Proportional Phase Incrementation (TPPI) of the rf Phase and an rf Phase cycle (0, π) are presented. The validity of the analytical description of the rf-driven ESEEM experiment is shown by comparison with experimental results.
