摘要：

We demonstrate by electron energy-loss measurements that the vibrational motion in the physisorption well is dipole active. This is a general phenomenon and data for adsorbed H-2, D-2, and HD reveal a strong nonlinear dependence of the induced dipole moments on displacement. We find that a good estimate of the dipole moment function can be obtained from a van der Waals model.
