The boxes are labeled by ranges within the infrared spectrum, representing the wavelengths at which specific functional groups absorb energy. The scale is shown in wavenumbers, cm-¹. Classify each functional group according to the approximate range where it would produce a stretch on the spectrum. Note: The stretches of the functional groups may not fill the entire range. 3700-3200 cm-¹ 3200-3000 cm-¹ C-H aromatic O-H alcohol 3000-2500 cm-¹ C=O aldehyde 2500-2000 cm-¹ 2000-1800 cm-¹ 1800-1600 cm-¹ Answer Bank C=N nitrile
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
