mass spectrometry. For the latter the essential doubleladder motif is maintained for all n in the solid state, but subtle changes in alignment of the ladder planes occur. Separation between the two layers of the doubleladder ranges from approx. 8.7 Å (for 25, n=5) to approx. 15 Å (for 30, n=12). In solution there is some dissociation of the doubleladders into the corresponding dimers. The degree of
