Quantum mechanics plays a central role in our understanding of fundamental phenomena, primarily in the microscopic domain. It lays the foundation for an understanding of atomic, molecular, condensed matter, nuclear and particle physics.

Topics covered include:

• the basic principles of quantum mechanics (probability interpretation; Schrödinger equation; Hermitian operators, eigenstates and observables; symmetrisation, antisymmetrisation and the Pauli exclusion principle; entanglement)
• wave packets, Fourier transforms and momentum space
• eigenvalue spectra and delta-function normalisation
• Heisenberg uncertainty principle
• matrix theory of spin
• the Hilbert space or state vector formation using Dirac bra-ket notation
• the harmonic oscillator
• the quantisation of angular momentum and the central force problem including the hydrogen atom
• approximation techniques including perturbation theory and the variational method
• applications to atomic and other systems.

The subject builds on the skills base established in CHEM20020 Structure and Properties. The concepts of quantum chemistry, statistical mechanics, molecular interactions and reaction kinetics will lay the fundamentals for the discussion of chemical reactions involving various types of reactive intermediates. The application of molecular orbital theory will be used to understand the nature of pericyclic reactions and the concept of coordination in main group (including carbon) and transition metal elements. An investigation of inorganic reaction mechanisms will focus on transformations involving coordination and organometallic complexes of d-block metals. Discussion of synthetic aspects will cover methods for carbon-carbon bond formation and functional group transformations, as well as principles of catalysis involving transition metal complexes and their chemistry in synthetic and biological systems.

This subject provides a series of specialised modules in the areas of organic, inorganic and physical chemistry.

Students choose three modules from the following selection of topics. Each module consists of 12 lectures.

• Physical Organic Chemistry,
• Methods in Organic Synthesis,
• Quantum Mechanics in Chemistry,
• Computational Chemistry,
• Supramolecular and Structural Inorganic Chemistry
• Metal Ions in Biology and Medicine

This subject will build on the experience gained in second year practical chemistry through the synthesis and characterisation of complex molecules, the acquisition and interpretation of advanced spectroscopic and physical data and the investigation of chemical systems through computational techniques. It consists of a series of laboratory-based experiments aimed at developing skills in the synthesis, safe handling and analysis of chemical substances of a range of different classes of compounds; an understanding of modern characterisation techniques (e.g. chromatography, atomic and molecular spectroscopy); and the operation of instrumentation for the acquisition of kinetic, structural and thermodynamic data.

A component of this subject will also involve the development of skills in independent practical work through the design and implementation of experimental procedures and techniques, and data interpretation. The subject will also provide opportunities for the development of scientific writing and presentation skills, problem solving and small group collaboration, while introducing resources and software commonly used within chemical research fields (i.e. scientific databases, chemical drawing software, molecular modelling & optimisation, etc).

In addition to increased proficiency in standard techniques, this subject provides an introduction into research-based chemistry through integrated and themed experiments. It will provide skill development in a range of techniques utilised in the modern chemistry laboratory.

The subject provides experience across multiple traditional chemical disciplines whilst highlighting the importance of these disciplines in diverse 'real world' applications such as materials science and medicinal chemistry.

The subject offers a range of projects in modules that offer experience in laboratory techniques and computational methods; the relative weights are indicated in the module descriptions. Students must select four projects with a combined weighting that contains at least 25% Computational Physics and 25% Laboratory Physics. The laboratory projects include nuclear physics, particle physics, diffraction, electronics, atomic physics, optical physics and astronomy. The computational projects are designed to develop programming skills and to introduce a range of numerical methods commonly used in physics research will be based on model problems in physics; these may include electronic structure theory, molecular vibrations, stellar structure, quantum spin systems, large-scale magnetic systems and gravitational lensing by point masses. Some projects may be offered that merge laboratory and computational work with approximately equal weighting.
