mass spectra - the M+1 peak
What causes the M+1 peak?
What is an M+1 peak?
If you had a complete (rather than a simplified) mass spectrum, you will find a small line 1 m/z unit to the right of the main molecular ion peak. This small peak is called the M+1 peak.

Given integer n>1, prove that we can find integer k>1 and a1, a2, ......ak >1 such that
a1 + a2 +........ak = n(1/a1 + 1/a2 +....1/ak)
