Quadrupole mass spectrometers typically provide a mass bandpass, Δm, of 0.5–0.7 amu, that is constant across all masses. The mass spectral resolution is insufficient to resolve the vast majority of potential spectral overlaps due to elemental or molecular ions from the elemental, analyte ion of interest.
A non-zero quadrupole term indicate deviations from a spherical mass distribution. The quadrupole tensor is quite distinct from the moment of inertia. Any non-point mass object will necessarily have a non-zero moment of inertia tensor. On the other hand, any object with a spherical mass distribution looks just like a point mass …
