Abstrakt: |
Dynamic nuclear polarization is combined with temperature-jump methods to develop a new 2D 13C-13C NMR experiment that yields a factor of 100-170 increase in sensitivity. The polaization step is performed at 100 K, and the sample is subsequently melted with a 10.6 microm laser pulse to yield a sample with highly polarized 13C spins. 13C detected 2D 13C-13C spectroscopy is performed in the usual manner. |
