Ultraviolet–visible (UV-vis) spectroscopy: Explanation of colour
Why do some compounds appear certain colours? The electron configuration of transition metal complexes is essential in understanding their behaviour. Understand the theory of how d-orbitals influence colour through their shape and crystal field splitting

Ultraviolet–visible spectroscopy (UV-vis): The origin of colour in organic compounds
DIscover how unsaturation in organic compounds leads to colour. Such electon configuration allows transitions between orbitals of lower energy and antibonding orbitals occur when electromagnetic radiation of suitable energy is absorbed by the molecule.

Infrared (IR) spectroscopy
Absorption of infrared radiation brings about changes in molecular vibrations within molecules and ‘measurements’ of the ways in which bonds vibrate gives rise to infrared spectroscopy. Atom size, bond length and bond strength vary in molecules and so the frequency at which a particular bond absorbs infrared radiation will be different over a range of bonds and modes of vibration.
