Identifying compounds from infrared and mass spectra (A level…
WebInfrared (IR) spectroscopy is a technique used to identify compounds based on changes in vibrations of atoms when they absorb IR of certain frequencies. A spectrophotometer irradiates the sample with IR radiation and then detects the intensity of IR radiation absorbed by the molecule. Symmetrical molecules such as O 2 or H 2, are therefore IR ... WebWorked example: Identify the functional groups in the molecule C6H12O2, using the infrared spectrum given below. (2 marks) Infrared (IR) Spectroscopy. Answer: Signal at 3230-3350 shows an O-H (alcohol) (1) and C=O at 1680-1750 (1) There are separate -OH and C=O bonds in the molecule, so it is not a carboxylic acid. data warehouse for power bi
