Spectroscopy in a Suitcase: UV-Vis teacher resources
UV-visible spectroscopy is a technique that readily allows one to determine the concentrations of substances and therefore enables scientists to study the rates of reactions, and determine rate equations for reactions, from which a mechanism can be proposed. As such UV spectroscopy is used extensively in teaching, research and analytical ...

Spectroscopy in a Suitcase: IR teacher resources
One of the first scientists to observe infrared radiation was William Herschel in the early 19th century. He noticed that when he attempted to record the temperature of each colour in visible light, the area just beyond red light gave a marked increase in temperature compared to the visible colours. ...

Spectroscopy in a Suitcase students' resource: spectroscopy introduction
Spectroscopy is the study of the way light (electromagnetic radiation) and matter interact. There are a number of different types of spectroscopic techniques and the basic principle shared by all is to shine a beam of a particular electromagnetic radiation on to a sample and observe how it responds to ...
