Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following best describes what infrared spectroscopy measures?
The absorption of visible light by a molecule.
The vibration of covalent bonds within a molecule.
The emission of X-rays from an atom.
The deflection of charged particles in a magnetic field.
2. In infrared spectroscopy, the region of the electromagnetic spectrum used is the region.
3. The 'fingerprint region' in an IR spectrum is typically found between cm⁻¹.
4. All molecular vibrations absorb infrared radiation.
True
False
5. Briefly explain why a C=O (carbonyl) stretch typically appears at a higher wavenumber than a C-O (ether) stretch in an IR spectrum.
6. The image above shows an infrared spectroscope. In your own words, describe the basic function of each major component of an IR spectrometer (e.g., source, sample cell, detector).
