In order to evaluate this source of nonlinearity, we can use the advantage that the linear case is invariant with respect to the change c(t) [right arrow] -c(t) which describes inversion symmetry of the point group [C.
The labeling of the molecular states with [sigma], which is either gerade (g) or ungerade (u), is a result of the inversion symmetry of all electrons through the center of mass of the molecule.
13 and 14, but we can say with certainty t hat the Ti-O environment changes from one with inversion symmetry to one that is strongly non-inversion symmetric.
