Chapter 17 Spectroscopy Flashcards
1
Q
The amount that a bond stretches or bends depends on
A
- mass of the atoms in the bond - heavier vibrate more slowly
- strength - stronger vibrate faster
2
Q
molecular ion
A
The positive ion formed in mass spectrometry when a molecule loses an electron.
3
Q
fragmentation
A
The process in mass spectrometry that causes a positive ion to spilt into smaller
pieces, one of which is a positive fragment ion.
4
Q
fragment ions
A
Ions formed from the breakdown of the molecular ion in a mass spectrometer.
5
Q
infrared spectroscopy
A
An instrumentation method of analysis that identifies bonds from absorption of the infrared radiation of different wavelengths.
6
Q
fingerprint region
A
An area of an infrared spectrum below 1500 cm–1 that gives a characteristic pattern for different compounds.
