1. Anharmonicity Until this point, we have been using the harmonic oscillator to describe the internuclear potential energy of the vibrational motion

2. Therefore, a lesion of the abducens nucleus always leads to a gaze palsy to the ipsilateral side, and a lesion of the MLF to an internuclear ophthalmoplegia (Fig. 5, 7).

3. Potential curves of the states B and C intersect adiabatically with a potential curve correlated to Xe* + Cl at large internuclear distances: 7.1 nm experimentally and 7.19 nm and 6.3 nm theoretically.

4. In high-density polyethylene (HDPE) and in ultradrawn ultrahigh molecular weight polyethylene (UHMWPE) fibers, the changes in the 13C−13C dipolar couplings brought about by the reorientations of the 13C−13C internuclear vectors in the Crystallites were observed
