All the results are shown for the neutral molecule and it is therefore necessary to specify the ionization method. The methods may be entered as a comma separated list of all the allowed ionizations.
You may as well specify multiple charges. Here are some examples of allowed patterns:
- H+ (addition a proton)
- H+, Na+, K+ (either a proton, sodium cation or potassium cation)
- H+, (H+)2, (H+)3 (addition of one, two or three protons)
- (H+)-1, (H+)-2, (H+)-3 (removal of one, two or three protons)
It is also allowed to enter a range
- (H+)1-10 (addition of one to 10 protons)
- (H+)-1–10 (removal of one to 10 protons)
