Quantum coherence spectroscopy to measure dietary fat retention in the liver
... In the present study, the use of both the 1D ge-HMQC and the 1D ge-HSQC was investigated. Identical to the above described reasoning, the intrinsic TE in the 1D ge-HSQC is shorter than in the 1D ge-HMQC. In practice, the ...
