The complete assignment of 19 F, 1 H and 13 C NMR spectra for a monosubstituted octafluoro[2.2]paracyclophane derivative is described for the first time. The unambiguous assignments were achieved through the combination of 19 F 1 H HOESY, 1 H COSY and 19 F COSY techniques and then further confirmed employing a complementary approach using a Karplus‐dependent 3 J CF interaction. Interesting aspects of the coupling patterns for various J HH , J HF , J CF and J FF interactions are also discussed. Copyright © 2005 John Wiley & Sons, Ltd.
