Ir Functional Group
Functional Groups We have seen that IR is really a “Functional Group Detector.” As such, it will be a valuable tool throughout this year. You should become accustomed to examining an IR spectrum and looking for characteristic bands that indicate the presence of a Functional Group.

Our Department offers B.S. Chemistry and B.S. Biochemistry majors, which are professionally accredited by the American Chemical Society.Our students also enjoy student-faculty interactions, educational opportunities, and comparatively low tuition that make us an appealing educational option.
Infrared Spectroscopy. 1. Introduction As noted in a previous chapter, the light our eyes see is but a small part of a broad spectrum of electromagnetic radiation.
The Role of Functional Groups. In organic chemistry, a functional group is a specific group of atoms or bonds within a compound that is responsible for the characteristic chemical reactions of that compound.
The spectrum for the ketone, 2-pentanone, appears below. It also has a characteristic carbonyl band at 1700 cm-1.The CH stretch still appears at about 3000 cm-1, and the CH2 bend shows up at approximately 1400 cm-1.
