Title

Deciphered Chemical Shifts in Aliased Spectra Recorded with two Slightly Different Narrow Windows or Differential Chemical Shift Evolution

Authors
Published in ChemPhysChem. 2010, vol. 11, no. 12, p. 2503 - 2505
Abstract The overlap of two HSQC spectra recorded with 10 and 9.9 ppm carbon spectral windows gives rise to highly resolved signals with a pattern providing unambiguous precise and accurate chemical shifts (see picture). Alternatively, the new DENA-HSQC pulse sequence takes advantage of a differential evolution of carbon chemical shift to do the same in a single experiment. Combined with multiplicity edition, DENA-HSQC advantageously replaces commonly used 1D DEPT-135 experiments.
