Question

What is the wavelength of fingerprint region?

• A. 100–500 cm\(^{-1}\)
• B. 500–1500 cm\(^{-1}\)
• C. 1700–2000 cm\(^{-1}\)
• D. 400–800 cm\(^{-1}\)

Hint:

The fingerprint region is vital in IR spectra for distinguishing between similar molecules.

Answer 1

The Correct Option is B

The fingerprint region in IR spectroscopy lies in the range of 500–1500 cm\(^{-1}\). This region contains complex absorption patterns unique to each compound, which helps in compound identification.
