Procedure by which translational energy spectra are obtained from a sector mass spectrometer that incorporates at least one magnetic sector plus one electric sector in reverse geometry (a magnetic sector followed by an electric sector).
Notes:
- In this context, kinetic energy is interpreted as translational rather than vibrational or rotational kinetic energy.
- The accelerating potential, \(V\), and the magnetic flux density, \(B\), are set at fixed values to m/z select the precursor ions, which are then allowed to dissociate or to react in a field-free region between the two sectors. The translational energy-to-charge ratios of the various product ions are analyzed by scanning the electric sector field \(E\). The width of a product ion spectral peak is related to the kinetic energy release distribution for the dissociation process.
