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. [1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on …

IR Spectroscopy; Table of IR Spectrum Frequency Values IR Spectrum Stretching Vibrations. Bond Order: Frequency: Structural Unit: Appearance of the Peak: Single Bonds: 3200–3600: O-H (Alcohol) Broad: 2500–3350: O-H (Carboxylic acids) Broad and zig-zagged: 3300–3500: N-H (Primary or secondary Amine)

2023年2月11日 · Be able to read and understand the data table for IR spectroscopy; As stated in the previous section, similar bonds will show up grouped near the same frequency because they tell us about the presence or absence of specific functional groups in a sample. ...
