Energy is inversely related to wavelength, so infrared light has less energy than visible light Typical units in infrared spectroscopy are wavenumbers ν – the reciprocal of the wavelength in centimeters 2,5 µm = 2,5 x 10-4 cm =4000 cm-1 25 µm = 2,5 x 10-3 cm =400 cm-1 Thus your typical IR spectrum runs from 4000 to 400 cm-1

The IR Spectrum Table is a chart for use during infrared spectroscopy, The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups, There are two tables grouped by frequency range and compound class, IR Spectrum Table by Frequency Range, Use this table when you already know the frequency of your material, Find the frequency range in the
Infrared Spectroscopy Absorption Table
Thus a sample that did not absorb at all would record a horizontal line at 100% transmittance top of the chart, Frequency – Wavelength Converter; Frequency in cm-1 Wavelength in μ : The frequency scale at the bottom of the chart is given in units of reciprocal centimeters cm-1 rather than Hz, because the numbers are more manageable, The reciprocal centimeter is the number of wave cycles
· FTIR Basic Organic Functional Group Reference Chart PDF Functional groups are structural units within organic compounds defined by specific atom and bond arrangements Infrared is a powerful identification tool for functional groups because of the similar absorption frequencies for those groups in different molecules The actual frequency is affected by the environment so the reference

Infrared spectroscopy correlation table
An infrared spectroscopy correlation table or table of infrared absorption frequencies is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups, In physical and analytical chemistry, infrared spectroscopy IR spectroscopy is a technique used to identify chemical compounds based on the way infrared …
FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy, In infrared spectroscopy, IR radiation is passed through a sample, Some of the infrared radiation is absorbed by the sample and some of it is passed through transmitted, The resulting spectrum represents the molecular absorption and transmission, creating a molecular fingerprint of the sample, Like a

A Fourier transform infrared FTIR spectrometer is an ideal tool for the identification of unknown organic and inorganic samples whether they exist in the form of a gas liquid or a solid ELECTROMAGNETIC SPECTRUM Radiation in the infrared region is commonly referred to in terms of a unit called a wavenumber ν rather than wavelength λ, Wavenumbers are expressed as reciprocal
