Rotational Raman spectra
The first requirement is that the polarizability of the molecule must be
anisotropic (it must depend on the orientation of the molecule).
Raman spectroscopy is less restrictive than pure rotational spectroscopy, as
linear symmet
Real boxes have finite depths to allow particle escape.
Moving x = 0 to the center:
V ( x ) = 0 for - a/2 < x < a/2
V ( x ) = V0 for x a/2 x -a/2
