    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.

  • dipole moment

    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

  • dispersive spectrometer

    Infrared (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

  • vibrational frequencies

    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.

    Introduction 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.

    Ultraviolet–visible (UV-vis) spectroscopy

    Learn how UV-visible radiation can be used to shed light on chemical identification and how our senses percept colour. From the theory behind molecular orbitals and electronic transitions to the application of this technique with relatable examples. Includes examples and interactive simulations to aid understanding.

  • nuclear magnetic resonance

    Nuclear magnetic resonance (NMR) spectroscopy

    Discover how nuclear magnetic resonance (NMR) spectroscopy works, with this series of topics breaking down the fundamental theory. Covering the electronic environment of atoms right up to demonstrating the practical identification of molecules. Includes examples and interactive simulations to aid understanding.

    On This Day - Nov 07 : Raman was born

    He was awarded the Nobel Prize in Physics in 1930 for his work on the scattering of light and the discovery of the Raman effect. This effect is the change in the wavelength of light when a light beam is deflected by molecules. Raman spectroscopy has since become a key tool for chemical characterisation.
