The reported K values were miscalculated. As such the apparent K values for the linear ‘trimer and tetramer’ are 9.5±5 × 10⁴ dm⁶ mol^-2, 2.4±1.4 ×10⁸ dm⁹ mol^-3, respectively. That of the closed tetramer is 7±2 × 10⁹ dm⁹ mol^-3. The phrase ‘discrete squares and tapes’ may be misleading, and a better phrase may have been ‘tapes and discrete squares’. Thus the paper by Ercolani¹ in this issue does not contradict our observations, but highlights the dynamics or complex equilibria involved in weakly bound systems—a known but important fact that we specifically pointed out. We thank this author for bringing this mistake to our attention.
