In IR spectroscopy, what does a peak at around 1700 cm-1 typically indicate?
Step 1: Understand what IR spectroscopy is. It is a technique used to identify functional groups in molecules by measuring how they absorb infrared light.
Step 2: Know that different functional groups absorb infrared light at specific wavelengths, which are measured in cm-1.
Step 3: Recognize that a peak at around 1700 cm-1 is a specific wavelength where certain groups absorb light.
Step 4: Identify that the peak at this wavelength is typically associated with carbonyl (C=O) groups.
Step 5: Remember that carbonyl groups are found in compounds like ketones and aldehydes.
