How to calculate m+1 peak
WebThe molecular ion peaks (M + and M+2) each contain one chlorine atom – but the chlorine can be either of the two chlorine isotopes, 35 Cl and 37 Cl. The molecular ion containing the 35 Cl isotope has a relative formula mass of 78. The one containing 37 Cl has a relative formula mass of 80 – hence the two lines at m/z = 78 and m/z = 80. Webcharco. This is statistics: I'll show you how to do this for a Cl 2 molecule... If you have two different types of atom in the element and their abundance ratio = 3:1 (as for example 35Cl and 37Cl) Then the probability of chosing your first atom as 35Cl is 3/4. The probability of chosing your second atom as 35Cl is also 3/4. So the probability ...
