What is Infrared Spectroscopy?
Infrared spectroscopy, or IR spectroscopy, is a method of spectroscopy used by organic chemists to help determine the structure of an unknown molecule. An IR spectrum will have peaks based on how...

Why do we use infrared light for spectroscopy?
Infared (IR) and the entire spectrum are used to excite molecules and cause them to gived off a signature of various wave lengths of light. Some things show up in the far red (invisible) band. Some...

How does infrared work?
The same way you do when you turn your flashlight on and off to send a message to a friend, only on the part of the light spectrum invisible to the human eye (below the red spectrum). If you have a...

How does infrared detectors work?
I believe infrared detectors measure heat being given off by an object. However since everything gives off heat.. the detectors have to be cooled down to very low temperatures themselves using liquid...

How atomic absorption spectroscopy work?
Firstly, the sample to be analysed is atomised and mixed with fuel in a nebuliser. It is then combusted providing the molecules and ions to become atoms. A hollow-cathode lamp containing the...
