The differences in energy between different states of bond vibrations in a molecule correspond to which electromagnetic region?

Correct answer: B. Infrared

  • A. Microwave
  • B. Infrared
  • C. Visible
  • D. X-rays

Explanation

The difference in energy between two vibrational states is equal to the energy associated with the wavelength of radiation that was absorbed, it lies in the infrared region, therefore the answer is B.

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.
