Cartesian coordinates dipole potentials

We consider a one-dimensional model with an active coordinate r — n — r2- The potential energy V(r ) curve and the components of the dipole moment are shown in Fig. 2. In the r2, subspace, we adopt a Cartesian kinetic energy operator with no cross-term what is justihed since both coordinates have no common atom. The corresponding masses are ji2 = 1 3 — with jic being the mass of a C atom. By taking linear combinations r — — T2 and...
