Infrared Spectroscopy (Exam 3) Flashcards
1
Q
What is the driving principle behind IR spectroscopy?
A
IR causes molecules to vibrate which causes bonds to bend and stretch.
2
Q
What is the selection rule of IR spectroscopy?
A
Dipole moment changes during molecular vibration in order to actually have infrared absorptions
3
Q
Oscillating fields are accompanied by oscillating dipoles { }.
A
Of the same energy
4
Q
What is a wavenumber?
A
The number of wavelengths per distance (just another term for radiation energy)
5
Q
What is the main use of IR spectroscopy?
A
Detecting functional groups
6
Q
What are the 3 major components of the Michelson Interferometer?
A
1) Fixed mirror
2) Moving mirror
3) Beam splitter
