It is shown that tickling and INDOR techniques can be used jointly under certain conditions to give information unattainable by other means. These conditions are that all the transitions involved shall be connected in chain. The experiment fails if they are connected as a branch. Under these conditions INDOR lines can be split by tickling or, as we can also say, doublets resulting from tickling can show up in INDOR spectra. The technique can be used to determine the sign of a lone, long-range coupling in a multispin system. It was applied to 2,4-dichlorobenzaldehyde, the results showing that the long-range coupling across five bonds is positive. © 1982.
