CHEM20120 Physical Chemistry (level 2)

Academic Year 2023/2024

This module aims to provide students with a critical understanding of the fundamentals and mathematical formulation of quantum mechanics and with a working knowledge of the quantum mechanical nature of atoms and molecules. The module has distinct parts, as follows:

The first part presents the key principles and techniques of quantum theory along with applications of the theory to relevant model systems. This knowledge is then employed to make a comprehensive description of (i) the internal structures of hydrogen-like and many-electron atoms, (ii) how atoms interact with light, and (iii) why atomic properties exhibit periodic trends.

The second part considers the origin of the strengths, numbers, and three-dimensional arrangement of chemical bonds between atoms. The electronic structure of molecules is analyzed in terms of two quantum mechanical theories, namely, valence bond theory and molecular orbital theory.

Learning Outcomes:

On completion of the module, students will be able to:
• Understand the origins of quantum mechanics in terms of energy quantization and wave-particle duality
• Describe the dynamics of microscopic systems in terms of the Schrödinger equation and the Born interpretation of the wavefunction
• Use key principles of quantum mechanics to determine the information in a wavefunction and to describe the nature and ramifications of the uncertainty principle
• Apply quantum mechanics to the description of translational motion, confinement (particle-in-a-box), tunneling, rotational motion (particle-on-a-ring and particle-on-a-sphere) and vibrational motion (harmonic oscillator)
• Describe the property of particle spin

Feedback Strategy/Strategies

• Group/class feedback, post-assessment

How will my Feedback be Delivered?

There will be four assignments based on problem solving with a particular emphasis on numerical skills development Tutor will provide in-person tutorials to describe aim of each question, relevance to lecture material, approach to solution, and worked solution Assignment questions will bridge between the in-class lecture material, the learning outcomes, and the end-of-trimester exam
