With respect to the classroom
discussions of spectroscopy, review/calculate/look up/answer each of the
following:
- Electromagnetic spectrum.
- Regions of the spectrum
- Photon/quantum
- Wave properties: amplitude, intensity, frequency,
wave length
- Mathematical relationships between energy,
frequency, and wavelength.
- Wave units.
- Definition of wave number
- The frequencies corresponding to 400nm and 750nm,
respectively
- The wave numbers corresponding 400nm and 750nm.
- Convert 3000 and 1850 wave numbers of wavelength,
expressed in microns (um)
- Using CO2, H2O, and CH4
as examples, explain what is meant by stretching and bending modes.
- Explain why the symmetric stretching mode for CO2
is infrared inactive and that of water is active.
- Cl2 is transparent to infrared but HCl is
not. Why?
- Summarize the relationship between frequency, force
constant for a chemical bond, and mass of that atoms involved.
- Compare the C-to-C stretching frequencies for
ethane, ethylene, and acetylene; the H-to-X stretching frequencies for
H-F, H-Cl, and H-Br.
- Which of the following would you expect to be
“greenhouse” gases: oxygen, ozone, CF2Cl2?
