High-resolution 1H NMR spectroscopy of fish muscle, eggs and small whole fish via Hadamard-encoded intermolecular multiple-quantum coherence.
BACKGROUND AND PURPOSE: Nuclear magnetic resonance (NMR) spectroscopy has become an important technique for tissue studies.Since tissues are in semisolid-state, their high-resolution (HR) spectra cannot be obtained by conventional NMR spectroscopy.Because of this restriction, extraction and high-resolution magic angle spinning (HR MAS) are widely a
