ResourceUltraviolet–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
-
ResourceUltraviolet–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.
-
ResourceUltraviolet–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.
-
ResourceInfrared (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.
-
ResourceInfrared (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
-
ResourceInfrared (IR) spectroscopy: Uses of IR spectroscopy
Infrared spectroscopy is a valuable technique in analytical chemistry. Learn about how spectra arise and the instruments used to measure them
-
ResourceInfrared (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.
-
ResourceIntroduction to spectroscopy
Get back to basics with this primer on the principles of spectroscopic techniques, including infrared (IR), ultraviolet-visible (UV-vis) and nuclear magnetic resonance (NMR). To make it even easier, each technique has clear explanations and descriptions supported by animations.
-
