09276 IUPAC Gold Book - relative instrument spectral response function 10.1351/goldbook.09276 09276 current acronym: RISR 1 In Auger electron spectroscopy (AES), secondary-ion mass spectrometry, and X-ray photoelectron spectroscopy, the spectrometer response function divided by the response function of a reference instrument, or the average for several such instruments, as a function of energy (AES, XPS, etc.) or mass (SIMS). The RISR can be used to relate spectra from one instrument to spectra from another when using similar excitation sources and geometries.
