Abstract
THERE are many short hydrogen bonds which have been claimed to be symmetrical, but it is only in the case of potassium hydrogen fluoride that all the experimental evidence indicates that the proton is central. Yet in this substance there are still some problems to be cleared up, one of them being the hypothetical divergence of the protonic vibrational levels. Besides, as will be shown, the experimental results, which were thought to be explainable only in terms of a symmetrical model, may be explained in another way.
