Aims and Objectives
Having successfully completed this module you will be able to:
- Set up glassware and apparatus to conduct experiments in Physical Chemistry.
- apply the steady state approximation and derive the rate law of a complex mechanism such as that found in unimolecular reactions.
- understand complex numbers and their use.
- write the rate of reaction taking into account the stoichiometry of all species, express a rate law for elementary processes
- apply selection rules to predict observed spectroscopic transitions
- Present the results of a practical investigation in a concise manner.
- integrate most functions encountered in chemical practice.
- complete operations involving matrices, including the determinant and transpose
- sketch energy level diagrams corresponding to spectroscopic transitions for the various spectroscopic methods covered
- understand and apply the Boltzman distribution and its effect on the observed spectra
- determine the order of reactions with respect to given species by applying the initial rate method and isolation method, express the rate law from the orders with respect to the species involved
- draw an energy versus reaction coordinate diagram, predict the dependence of rate constants on temperature, calculate the activation energy and preexponential factors
- calculate fundamental properties of molecules using spectroscopic data and similarly predict spectroscopic features given the fundamental properties
- determine rate constants and half-life for 0, 1st and 2nd order reactions from experimental datasets
- explain the concept of degeneracy
- Evaluate the risks associated with an experiment and understand how to mitigate against those risks.
- Interpret data from an experiment, including the construction of appropriate graphs and the evaluation of errors.
- solve separable first-order ordinary differential equations.
- explain the concept of a particle in a box and the solutions to the Schrödinger equation for particles in 1D, 2D and 3D boxes
- Kinetics: Rate expressions and rate laws for simple zero, first, and second order reactions; the concept of activation energy and its effect on the rates of chemical reactions
- Introductory Quantum Mechanics: the Schrödinger equation; particle in a 1D and 2D box; degeneracy.
- Radiation and Matter: The Electromagnetic Spectrum again; Absorption; Stimulated and spontaneous emission; Principle of the Laser; Raman and Rayleigh scattering; Types of spectroscopy.
- Ultraviolet and visible spectroscopy: Beer-Lambert law; Absorption/emission processes; Jablonski diagrams; Fluorescence and Phosphorescence
- Infrared and microwave spectroscopy: Vibrational quantum states; Selection rules for IR; Modes of oscillation; Rotation and moment of inertia; Linear rotor QM states; Rotational constant; Selection rules for microwave; PQR rotation vibration spectra; Rotational and vibrational Raman.
- Mathematical concepts in physical chemistry
- Completion of two practical experiments and associated reports covering a range of topics and skills that enable the understanding of the physical chemistry that underpins the reactivity of matter; reinforce key skills already introduced; understanding the importance of experimental safety and time management.

All absences from practical sessions must be validated. Unexcused absences will result in failure of the module.
Repeat year externally: allowed if practical component passed. The practical marks are retained, the theory assessment is exam only.
Repeat year internally: note that practical may be reassessed by resubmission of reports or repeated.
This is how we’ll give you feedback as you are learning. It is not a formal test or exam.Tutorial
This is how we’ll formally assess what you have learned in this module.
This is how we’ll assess you if you don’t meet the criteria to pass this module.
