TABLE 8.1 Some Easily Recognizable IR Absorption Patterns
Bond
Description of Peak
-C-H, where C is not part of a benzene ring Sharp, strong peak on the low side of 3000 cm", between about 2850
and 3000 cm
Sharp, medium peak on the high side of 3000 cm", between about 3000
and 3100 cm
Sharp, medium peak on the high side of 3000 cm", between about 3250
and 3300 cm
Broad, strong peak centered at about 3300 cm
-C-H, where C is part of a benzene ring or
double bond
-C-H, where C is part of a triple bond
-O-H, in alcohols, phenols, and water, for
example
-C=0, in aldehydes, ketones, etc.
-C-C-, in benzene rings
Sharp, strong peak at about 1700 cm
Two sharp, strong peaks near 1500 and 1600 cm", a series of weak peaks
(called overtones) between 1600 and 2000 cm", the latter in the case
of a mono-substituted benzene ring
