1
Q
molecular ion peak
A
indicates the species formed from the molecule by the loss of one electron
2
Q
fragmentation
A
occurs when the molecular ion breaks into smaller pieces
3
Q
base peak
A
indicates the peak with the greatest abundance
4
Q
infrared radiation
A
the part of the electromagnetic spectrum with frequencies below that of red light
5
Q
when does stretching occur?
A
when a bond absorbs infrared radiation and uses it to alter the length of the bond
6
Q
transmittance
A
transmittance value in an infrared spectrum represents the amount of radiation absorbed at a particular wavenumber
7
Q
wavenumber
A
represents the frequency of infrared radiation absorbed by a particular bond in a molecule
8
Q
intensity
A
describes the amount of infrared radiation absorbed
