Sticky Note
Which type of following spectroscopy commonly utilizes derivative spectroscopy for qualitative analysis of organic compounds?
  1. X-ray spectroscopy
  2. UV-Visible spectroscopy
  3. Raman spectroscopy
  4. Mass spectroscopy
Explanation

Derivative spectroscopy is commonly used in UV-Visible spectroscopy to:

- Resolve overlapping peaks

- Improve detection of minor spectral features

- Enhance qualitative analysis by identifying small changes in absorbance

This technique is especially helpful in complex mixtures or closely related compounds, where normal UV-Vis spectra might not show clear differences.
