Q
Q: In the context of IR spectroscopy, what does the term 'fingerprint region' refer to?
Solution: The 'fingerprint region' in IR spectroscopy refers to the region between 400-1500 cm-1, where many unique absorption bands occur for different compounds.
Steps: 6
Step 1: Understand that IR spectroscopy is a technique used to identify compounds based on how they absorb infrared light.
Step 2: Know that different compounds absorb light at different wavelengths, creating a unique pattern.
Step 3: The 'fingerprint region' is a specific part of the IR spectrum.
Step 4: This region is between 400 and 1500 cm-1.
Step 5: In this region, many unique absorption bands appear, which can help identify specific compounds.
Step 6: Think of the fingerprint region like a unique signature for each compound.
