HYDROGEN MOTIONS IN SHORT HYDROGEN-BONDS

We studied the hydrogen-bond-length dependence of the asymmetric term in the hydrogen potential by the numerical calculation, and explained some isotope effects such as the Ubbelohde effect which was generally observed in various hydrogen bonded compounds. Furthermore, we observe d the hydrogen excitation spectra as well as the Q-maps of the neutron scattering function of short hydrogen-bonded compounds with incoheren t neutron scattering experiments, and extracted the shapes of the hydr ogen wave functions from these data. The extracted shapes were compare d with the calculated ones derived from the proposed hydrogen potentia l.
