Abstract

The homonuclear dipolar coupling of a directly bonded 13C[BOND]13C pair has been used to create a dipolar double-quantum filter (D-DQF) to remove the natural-abundance 13C background in 13C{2H} rotational-echo double-resonance (REDOR) experiments. The most efficient version of this experiment has the D-DQF excitation and reconversion preceding the REDOR evolution period. Calculated and observed 13C{2H}D-DQF-REDOR dephasings were in agreement for a test sample of mixed recrystallized labeled alanines. Copyright © 2007 John Wiley & Sons, Ltd.
