NMR Spectroscopy of Polymers

molecular tumbling causes that anisotropy of nuclear interaction now plays dominant role in the appearance of NMR spectra. Frankly speaking the NMR signals are very broad and spectra become featureless. In general missing isotropic tumbling leads to severe broadening of the detected signals. The lack of resolution, however; does not mean the absence of structure information, it rather reflects ...

NMR Spectroscopy in Microfluidic Stripline NMR Chips

Microfluidic stripline NMR technology not only allows for NMR experiments to be performed on small sample volumes in the submicroliter range, but also experiments can easily be performed in continuous flow because of the stripline’s favorable geometry. In this study we demonstrate the possibility of dual-channel operation of a microfluidic stripline NMR setup showing oneand twodimensional H, C ...

Ultrahigh-Resolution NMR Spectroscopy**

Spectral resolution is vital in NMR spectroscopy, but is instrument-limited. Recent “pure shift” pulse-sequence developments greatly improve resolution, but often at a high cost in sensitivity. We introduce a new class of pure shift experiments (PSYCHE) with superior sensitivity, spectral purity, and tolerance of strong coupling. The key parameters for any spectroscopic technique are sensitivit...

NMR/NQR Spectroscopy

The NMR/NQR group has continued its general research plan of studying current problems of condensed matter physics by employing NMR (nuclear magnetic resonance) and NQR (nuclear quadrupole resonance) methods. These spectroscopies allow one to investigate electronic properties in solids at a microscopic level and thus provide an essential contribution for a better understanding of the materials ...
