What is the approximate wavenumber of the functional group region where functional groups exhibit their IR bands? What about the fingerprint region?
Homework Answers
The approximate wave number ranges from 4000 to 650 cm-1.
Now finger print region is somewhat a complex region of IR spectroscopy.Firstly it ranges from 1500 - 500 cm-1 in the right hand region of spectrum.It is the region where all the bending vibrations are recorded.It is so called because this region helps us to recognise unknown molecules.Even if 2 molecules howsoever closely related can be distinguished in this region hence called as finger print region.

find each major functional group peak, identify the
fingerprint region.
so far i think that there is a saturated C-H at
~2900cm-1 and a carbonyl group at ~1300 cm-1.
