The spectrum of Si2 B2PFSCI6 was identified by use of precise mass measurement. WebThe 13 C isotope is, of course, heavier than 12 C by 1 mass unit. In addition, about 0.015% of all hydrogen atoms are actually deuterium, the 2 H isotope. So the M+1 peak represents those few acetone molecules in the sample which contained either a 13 C or 2 H. Molecules with lots of oxygen atoms sometimes show a small M+2 peak (2 m/z units ...
