This model considers the molecular partition function as the product of the contributions of four independent degrees of freedom, nuclear ( n ), vibration ( vib ), rotation ( rot) and electronic ( el ): III.43 is the elec-tronic partition function. 8. According to the auf bau principle each electron occupies the lowest energy orbital Z* for O 2s and 2p orbitals are similar so the AOs start at nearly the same energy Label all atomic and molecular orbitals and fill in the valence electrons from both atoms in this case, the energy of, is less than energy of o a Page 1 of 22 Analytical expression of partition function obtained for the system is used to derive equations of molar entropy and Gibbs free energy.

Rotational Partition Functions Linear Molecules The rotational energy and degeneracy of a linear molecule is given by where J= 0, 1, 2,m and Iis the moment of inertia The first page of this article is displayed as the abstract. The so called internal or molecular partition function for the diatomic molecules, for most of the applications, is composed of three independent partition functions that are the electronic, the vibrational, and rotational some results are given for the electronic partition function in Schadee (1964).

I need to calculate the partition function of N2 C state. As Compared with previous publications, the number of diatomic electronic states considered in our work is as large as possible. The electronic function, e(r,R), is a function of both the nuclear and electronic coordinates, but only depends upon the electronic quantum number or electronic state, e. Translational and rotational motion is not included here. The electronic partition function is, as before, expressed as Here we assume that only the ground electronic state contributes, and notice the zero of the energy is given at the bottom of the well and Deis the dissociation energy. Vibrational Partition Functions The inclusion of molecular vibrations will effect the partition function which, in addition to the electronic contribution, will contain the vibration part [28]. The equipartition theorem is also known as the law of equipartition, equipartition of energy, or simply equipartition.
