The tiny size of conventional diatomic molecules in the sub-nanometer regime hinders direct optical resolution of their constituents.
The diatomic gas molecule's vibrational energy would be related to the absorption and/or emission of its surrounding blackbody/thermal radiation at temperature (T).
There is no question that, for the hydrogen atom, the squared angular momentum should be based on l (l + 1), as Schroedinger (1926a) obtained, but a diatomic molecule is an entity with properties distinct from those of a hydrogen atom, even if there be a formal correspondence between the Coulomb problem and a quadratic harmonic oscillator in multiple dimensions (Kostelecky et alii, 1985).
The vibration rotation energy of an electronic state of a diatomic molecule is commonly represented by [E.sub.vJ] = [E.sub.v] + [lambda][B.sub.v] + [[lambda].sup.2][D.sub.v] + [[lambda].sup.3][H.sub.v] + [[lambda].sup.4][L.sub.v] + [[lambda].sup.5][M.sub.v] ..., where [lambda] = J(J + 1), v and J are, respectively, the vibrational and rotational quantum numbers, [E.sub.v] is the pure vibrational energy, [B.sub.v] the rotational constant, and [D.sub.v], [H.sub.v], [L.sub.v] + ...

In this paper, we present an alternative proposal to the understanding and interpretation of the dipole moment of diatomic molecules, present content in the curriculum of physical chemistry and quantum chemistry disciplines in undergraduate chemistry courses.
Its involvement in so many biological processes, its simple diatomic structure and highly reactive nature enables it to form various complexes with other cellular components (Bogdan, 2001).
