Webatomic mass unit (AMU or amu): An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. WebThis is known as the M+1 peak and comes from the few molecules that contain a 13 C atom in place of a 12 C. A molecule containing one carbon atom will be expected to have an M+1 peak of approximately 1.1% of the size of the M peak, as 1.1% of the molecules will have a 13 C rather than a 12 C.
