Infrared spectroscopy
1
Q
In infrared spectroscopy, what changes are made to molecules to test for frequencies they absorb?
A
Vibrational energy changes, with infrared radiation.
2
Q
What is wavenumber?
A
1/𝜆 measured in cm-1.
3
Q
What is wavenumber directly related to?
A
The frequency of infrared absorption.
4
Q
What is the fingerprint region on an infrared spectrum?
A
The part below 1500cm-1, where characteristics of specific molecules can be seen.
5
Q
What type of compounds tend to exhibit complex absorption patterns in the fingerprint region?
A
Aromatic compounds.
