Splitting Light: Spectroscopy

Comments (0)

A Catalyst article looking at which type of radiation is absorbed and emitted through spectroscopy. This is the study of the wavelengths of light which allows us to identify the substances present in the source. This investigation provides a lot of useful information about a compound. It is used in a very wide variety of applications, from helping chemists to work out the structure of a new molecule they have made, to testing for drugs, forensics testing and quality control. In the article two case studies look at iodine in milk and breath tests.

This article is from Catalyst: GCSE Science Review 2011, Volume 21, Issue 4.
