Calculate the fraction of molecules in each of the rotational
energy level J=0, 1, 2 and 3 for O2 at its normal boiling
temperature, 90.1 K. An oxygen tom has a nuclear spin number mN=0
(so-called magic nucleus) and atomic weight
16 (8 protons and 8 neutrons). It may be assumed that all the O2
molecules are in the ground electronic state, for
which the electronic wave function Ψ" is antisymmetric with respect
to the nuclear exchange.
Homework Answers
I just give the general idea how to solve this kind of
questions.Calculation can be done by anyone easily thats not the
matter at all.
