Notes:
Reasons for the low reliability of the Compare e.g. former results cited in [3][4] with our results in [3].H-NMR estimation of the dimerisation constant of caffeine in D2O are discussed. The main reasons are (1) strong influence of small variations in the monomer shifts δ0 which are to be determined by extrapolation, and (2) disturbance by the formation of higher oligomers. The dilemma ist that attempts to minimize errors from (1) increase the influence of (2) and vice versa.
