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

Resource
Ultraviolet–visible (UV-vis) spectroscopy: Colour in transition metal compounds
Transition elements are found in the d-block of the periodic table and the most interesting feature of transition metal compounds is that most are highly coloured.

Resource
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: More complicated molecules
Learn about the fundamental physics responsible for the IR spectra of more complicated molecules. Bringing together vibrational modes, bond strengths and dipole moments — and how these translate to the recorded spectra.
-
Resource
Infrared (IR) spectroscopy: Energy levels
Infrared spectroscopy reflects the type of bonding present within a molecule, learn how the energy levels of bond vibrations and dipole moments contribute to the frequencies observed
