The NMR spectra of the square-planar silver(III) anions and were investigated. The [ Ag(CF 3 ) 4 ] -[ Ag(CF 2 H) 4 ]signs of 1J(109Ag,13C), 2J(109Ag,19F) and 2J(109Ag,1H) and those of the long-range couplings 4J(19F,19F), 3J(19F,13C), 3J(13C,1H) and 4J(19F,1H) were determined by analysis of higher o

## Abstract Analysis of the noise decoupled ^13^C spectra of doubly ^13^C labelled compounds where the two labelled carbons are identical, makes the determination of reltive signs of ^13^C^13^C coupling constants possible in a very simple way. The involved carbon form AA'X or AA'B spin systems.
