* Define the terms 'wavefunction' and 'eigenvalue'.
* Relate physical models to quantisation of molecular and electronic energies.
* Use quantum mechanical methods to generate and rationalise the structure and bonding in organic molecules.

To be able to manipulate and plot current/voltage data and interpret the graph.

Basic principles of quantum mechanics; wavefunctions, eigenvalues and operators. Solving the Schrödinger equation and the calculation of energy levels. Development of the variation method applied to diatomic molecules and hydrocarbons. Calculation of electronic and bonding energies. The relationship between molecular orbitals, electron density and reactivity.
Classification and types of polymers. Synthesis of polymers with examples taken from several different classes (addition, step-growth, ring opening, organometallic) with the emphasis on how physicochemical considerations influence the polymer structure. Characterisation of polymers (molecular weight and chain length, spectroscopy, thermal methods). Structure and morphology of polymers and how this influences properties. A survey of recent applications taaken from current research and industrial topics.
Applications of electrochemistry, reference electrodes, the electrical double layer, the background electrolyte, redox reactions and their thermodynamics, the differences between two and three electrode measurements, the role of a potentiostat and the rate determining step in electrochemical reactions (kinetics of electrochemical reactions and diffusion limited reactions). We will also look at some common electrochemical analysis techniques such as cyclic voltammetry and interpret the current-voltage responses obtained.
