Optical spectroscopy is a great way to demonstrate the fundamental principles of the absorption and emission of radiation - the fundamentals of spectroscopy. Its visual and easy to demonstrate. Thanks to funding from the RSC via the Chemistry: the next generation and HE-STEM programmes we have put together a set of equipment as part of "Spectroscopy in a Suitcase". This equipment is available for loan schools to allow pupils hands-on access to the equipment.
Full details can be found at our Spectroscopy in a Suitcase page.
