Infrared spectroscopy is the study of the interaction of infrared light with matter. The fundamental measurement obtained in infrared spectroscopy is an infrared spectrum, which is a plot of measured infrared intensity versus wavelength (or frequency) of light.
23 Νοε 2016 · The Two Main Things To Look For In An IR Spectrum: “Tongues” and “Swords”. Alcohols and Carboxylic Acids: More Detail. Specific Examples of IR Spectra of Carbonyl Functional Groups.

11 Φεβ 2023 · The IR spectrum is a graph where the x-axis is frequency and is labeled as wavenumber (cm-1). The y-axis is the amount of light absorbed and labeled as Transmittance (%). This is measuring how much light has been transmitted at a particular frequency.
By learning where characteristic functional-group absorptions occur, it’s possible to get structural information from IR spectra. Table 12.1 lists the characteristic IR bands of some common functional groups.
How to use an infra-red spectrum to identify a number of common bonds in organic compounds
16 Δεκ 2021 · With the basic understanding of the IR theory, we will take a look at the actual output from IR spectroscopy experiments, and learn how to get structural information from IR spectrum. Below is the IR spectrum for 2-hexanone.
An important tool of the organic chemist is Infrared Spectroscopy, or "IR". IR spectra are acquired on a special instrument, called an IR spectrometer. IR is used to gather information about compound's structure, assess its purity, and sometimes to identify it.
