Solid-state 13c cp/mas nmr spectra
WebThe 13C cross-polarization (CP) technique combined with magic angle spinning (MAS) has become one of the more commonly performed solid-state nuclear magnetic resonance (NMR) experiments. The basics of initially setting up the experiment are given and used to illustrate such NMR phenomena as rotational echoes, homogeneous WebIn order to understand the transition mechanism, we measured the temperature dependence of 1H CRAMPS solid state NMR and 13C CP/MAS spectra of D- and L-alanine crystals from 295K through to 220K.Obvious difference of NMR behaviors between two enantiomers was observed in the phase transition process.
