Preferred Label : charge-inversion mass spectrum;
IUPAC definition : Charge inversion processes of the types: or or respectively, occuring in a collision
cell (containing a gas, X) located in a field-free region preceding a magnetic and
electric sector combination placed in either order, may be detected as follows. If
the instrument slits are wide, and if the connections to the two sectors, appropriate
to transmission of either positive or negative main-beam ions, are simply reversed,
the negative or positive product ions of the two processes, respectively, will be
transmitted. If the magnetic field is scanned, a spectrum of such product ions will
be obtained, and this spectrum is called a charge-inversion mass spectrum. These spectra
are sometimes referred to as i E /i and i E /i spectra, respectively. The terms
'2 i E /i , i E /i /2, i E /i or i E /i mass spectrum' should not be used without
prior explanation of the meaning 2 i E /i , i E /i , i E /i or i E /i .;
