Which of the following radiations cannot cause excitation in the molecule ?

Correct answer: D. None of the above

  • A. Red Colour
  • B. Green Colour
  • C. Ultra Voilet
  • D. None of the above

Explanation

The answer is D as all the mentioned radiations can excite molecules.All electromagnetic radiation, including red and green colours of visible light, have the potential to cause excitation in molecules, although the likelihood of excitation increases with higher-energy radiation such as ultraviolet (UV) and X-rays. Therefore, all the options given in the question can cause excitation in molecules to some extent, and hence the correct answer is D) None of the above.

This question appeared on the ETEA MDCAT 2017 paper, which you can sit online with every answer explained.

About Spectroscopy and Analysis

Spectroscopy studies how substances absorb, emit or interact with electromagnetic radiation. Coverage includes ultraviolet-visible absorption, infrared identification of functional groups, Beer-Lambert law, spectral interpretation and the use of spectroscopic data to identify or determine the concentration of chemical substances.
