Infrared IR Spectroscopy (A-level Chemistry)

Показать описание

Outlining infrared spectroscopy (IR), the theory behind it and how it can be used in chemistry to analyse organic substances. Absorption of energy by covalent bonds and the use of IR spectra are shown, including why OH groups give broad absorbances. Examples of ethanol, ethanal and ethanoic acid are given.

For AQA, OCR (A), Edexcel and CIE.

Data table IR absorbance values used and shown are taken from AQA data booklet (7405).
