Important Concepts to Study:
Week 
Concepts 
8 
Understand the equations for the rotational spectra of
diatomic molecules using the nonrigid rotor model, the effect of
isotopic substitutions, population in rotational levels, principal
axes of rotation for nonlinear polyatomics and the corresponding
moments of inertia, Classification of nonlinear polyatomics into
various tops based on moments of inertia 
7 
Understand Boltzmann distribution, degeneracy of rotational
levels, application of the rigid rotor model to understand rotational
spectra of diatomic molecules. 
5 
Huckel molecular orbital theory as it applies to planar,
conjugate, polyenes 
4 
determine the ground state term symbol for any simple, heteronuclear
diatomic molecule or molecular ion, write wavefunctions for hybrid
orbitals 
3 
Complete wavefunction and the Hamiltonian for diatomic molecules,
determine the ground state term symbol for any homonuclear diatomic
molecule or molecular ion. 
2 
Write the complete wavefunction for H2+(this
means be able to do this week's homework on your own), understand
the connection between the mathematical and graphical representations
of the wavefunction for diatomic molecules, definitions of Coulomb
integral, resonance integral and overlap integral 
1 
Write the complete Hamiltonian for any diatomic molecule
and identify the individual terms, understand the BornOppenheimer
approximation and its implications, draw the potential energy curves
for H2 and H2+, recognize
that the potential energy curve is a sum of two curves, be able to
reproduce the potential energy curve for H2+
with the detailed information we learned in class.
