unit 3 section 4 organic analysis Flashcards
1
Q
what is the difference between mass spectrometry and high resolution mass spectrometry
A
high resolution mass spectrometry can accurately measure the atomic and molecular masses extremely accurately to several decimal places.
2
Q
explain how infrared spectrometry works
A
a beam of infrared radiation a sample of chemical. the infrared radiation is absorbed by the covalent bonds in the molecule, increasing their vibrational energy. bond between different atoms and bonds in different places in the molecule absorb different frequencies of infrared light
3
Q
what is the fingerprint region
A
it is a region between 1000cm-1 and 1550cm-1 on the spectrum
