""'Molecular Spectra and Molecular Structure IV . Constants of Diatomic Molecules " "'is a classic comprehensive multidisciplinary reference text contains a critical compilation of available data for all diatomic molecules and ions known at present publication-over 900 diatomic species in all; including electronic energies, vibrational and rotational constants, and observed transitions.

Stimulated emission can be modelled mathematically by considering an atom that may be in one of two electronic energy states, a lower level state ( possibly the ground state ) ( 1 ) and an " excited state " ( 2 ), with energies " E " 1 and " E " 2 respectively.

Because Enron dominated electronic energy trading, it " had enormous ability to swing those'forward'markets " to inflate prices, said Robert McCullough, an energy consultant, and the price drop following its bankruptcy filing was a " very clear " sign that " Enron may have been using its market dominance to set forward prices ."

The integrals above can be evaluated using the fact that the dependence of the integrals on \ mathbf { k } can be changed to dependence on \ epsilon through the relation for the electronic energy as described by the Free electron model \ epsilon ( k ) = \ hbar ^ 2k ^ 2 / 2m which yields for an arbitrary function G:
