Abstract
Partial ionization cross section (PICS) measurements, of the cations created through electron ionization from threshold to 100 eV, have been taken for 78 cationic fragments of R-carvone, using a HIDEN quadrupole mass spectrometer (EPIC 300) with a mass resolution of 1 amu. These PICSs correspond to the cationic fragments with the highest intensity signal registered in our R-carvone mass spectrum reported in Lopes et al. (Int. J. Mass Spectrom. 456, 116395 (2020)) and, to the best of our knowledge, are being presented here for the first time to the scientific community. We also associate the profile observed in the PICSs with some ionic fragmentation mechanisms for R-carvone, based on the appearance energy (AE) values found in Lopes et al.
