Ir functional group ranges
WebSince every functional group is composed of different atoms and bond strengths, vibrations are unique to functional groups, and classes of functional groups (e.g. O-H and C-H stretches appear around 3200 cm -1 and 2900 cm -1, respectively). A correlation chart with various functional group vibrations can be seen in Figure 3. WebDifferent functional groups absorb characteristic frequencies of IR radiation. Using various sampling accessories, IR spectrometers can accept a wide range of sam-ple types such as gases, liquids, and solids. Thus, IR spectroscopy is an important and popular tool for structural elucidation and compound identification. IR Frequency Range and ...
