Functional groups and their ir wavenumbers
WebAn 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. WebJan 29, 2024 · The first column lists the calculated harmonic wavenumbers (ν cal, cm −1) in increasing order, with their absolute (A) and relative (A%) infrared intensities in the second and third columns, respectively. The relative intensities were obtained by normalizing the computed value to the intensity of the strongest band.

WebStudy Notes. Notice that the scale at the bottom of the infrared spectrum for 2-hexanone shown is calibrated in wavenumbers (cm −1).A wavenumber is the reciprocal of a wavelength (1/λ); thus, a wavenumber of 1600 cm −1 corresponds to a wavelength of. 1 1600 cm − 1 = 6.25 × 10 − 4 cm or 6.25 μ m. Organic chemists find it more convenient to …
