(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.

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 ...

Nuclear Magnetic Resonance (NMR) spectroscopy is used for analysing organic compounds. Atoms with odd mass numbers usually show signals on NMR. For example, isotopes of atoms. Many of the carbon atoms on organic molecules are carbon-12. A small quantity of organic molecules will contain the isotope carbon-13 atoms.
