✦ Synopsis

The homonuclear dipolar coupling of a directly bonded 13 C-13 C pair has been used to create a dipolar double-quantum filter (D-DQF) to remove the natural-abundance 13 C background in 13 Cf 2 Hg rotationalecho 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 13 Cf 2 Hg D-DQF-REDOR dephasings were in agreement for a test sample of mixed recrystallized labeled alanines.
