label each major peak with a molecular formula (including
charge)
label the molecular ion peak as "M+" (if present)
label major peaks other than the molecular ion with three
things:
1) the mass to charge ratio
2) the structure or formula for that charged fragment
3) another formula to show which fragment was lost by the molecular
ion to form that ion
