100% transmission in IR spectroscopy means:
Correct answer: A. No absorption
- A. No absorption
- B. 50% absorption
- C. 75% absorption
- D. 100% absorption
Explanation
When IR radiation is passed through a sample, some of it is absorbed and some of it paasses through (transmitted). A 100% transmission means the sample does not absorb any IR radiation.

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.
