Abstract
In this article we stress the interest of performing precise
measurements concerning the IR spectra of H-bonds, as this has
been initiated under the impulsion of Professor Hadzi. We concentrate
on the few measurements which have been made of the
intensities of the ''s bands (X-H· · ·Y), which are highly cha-·
racteristic of H-bonds. These intensities have shown some intriguing
features: upon deuteration of the H-bond they often decrease
far more than expected. This is particularly marked for the
H-bonded cyclic dimers of carboxylic acids. It can be explained
by electrical anharmonicity but can also be a manifestation of
some cooperative effect between the two H-bonds of these dimers.
