Q
What is mass spectra used for?
A
Mass spectra can be used to identify the molecular mass of an organic compound and to gain further information about its structure.
2
Q
What are the peaks in mass spectrometry?
A
The m+ peak indicates the molecular mass of the molecular ion and original molecule
m+1 = ion
fragment ion peaks
–peaks represent positive charge
