Aromic Units, Why We Need Them and How They Work

Quantum Chemistry is usually carried out using Atomic Units, so a careful discussion of these units is warranted.

Electrostatics for Chemists

This is an introduction to electrostatics written for those interested in dipole moments, induced dipole moments, etc..

Eulerian Angles

Euler's angles are used to describe rotation using independent coordinates. They are useful in rotation spectroscopy studies, hence this introduction.

Compact Singlet S Helium Wave functions(corrected)

This is a corrected version of the Phys. Rev. A 74,14501 (2006) article. The result is improved slightly from that in the original paper.

Butadiene via the Huckel Scheme (using Maple)

The Huckel Molecular Orbtial method is used to treat the MO's of butadiene. The method employs analytical tools and Maple.

Nitric Oxide Equilibrium

The explicit formulas for following the passage to chemical equilibrium are derived.

Advance P. Chem. Problems (I) Populations, Partition Functions, Particle in Box, Harmonic Oscillators, Angular Momentum and Rigid Rotor

This is a set of P. Chem. problems posed at slightly higher than the normal text book level, for students who are continuing in the study of this subject.

A Review of Helium Hamiltonians

Helium Hamiltonian transformations are discussed in extreme detail.

More Than You Ever Cared to Know About Solution Thermodynamics

These readings are a compendium of earlier works put together and corrected for errors. The subject is solution thermodynamics, based on the one dimensional binary solution as "extended" to three dimensions.

Lee O. Case's "Elements of the Phase Rule", Chapter 1, One component systems

One component systems are treated from the point of view of the Gibbs' phase rule.

Constructed Response Answers in a Multiple-Choice Universe

A scheme is introduced which allows computer readable multiple choice forms used in traditional examinations to be employed for constructed response items.

Pauli Spin Matrices

The Pauli Spin Matrix representation of Spin Operators in Quantum Mechanics are explicitly demonstrated and illustrated in detail for one and two spin systems.

A Hartree-Fock Example Using Helium

The Hartree-Fock method is applied to Helium's electrons to show explicitly how the coupled equations reflect the interactions between electrons.

Invitation to Magnetism and Magentic Resonance, More on Magnetic Resonance

One and two spin systems are analyzed.

Molecular Mechanics of Water Monomer

Simulation of the classical molecular dynamics of a water molecule can be useful in explaining normal modes of motion, Fourier Transforms, and fundamental frequencies of vibration, as illustrated herein.
