Question

Microwave spectroscopy is generally used to detect:

• A. \( \text{Functional groups} \)
• B. \( \text{Double bonds} \)
• C. \( \text{Isotopes} \)
• D. \( \text{Unpaired electrons} \)

Hint:

Microwave spectroscopy provides insights into molecular rotational behavior and isotope differentiation.

Answer 1

The Correct Option is C

Microwave spectroscopy detects molecular rotational transitions, making it useful for isotope identification. Since isotopes have different atomic masses, their rotational spectra shift, allowing precise differentiation. Other methods, such as IR spectroscopy, are more suited for functional groups and double bonds.
