Two-dimensional intensity map of the time-dependent mass spectrum of the reaction of C3H6O+ with NH3. The reactant ion C3H6O+ appears at m/z = 58 and the primary product ion NH3 + appears at m/z = 17. Minor secondary products are observed at m/z = 34, 60, 75, and 90. The plot was made was collecting mass spectra at trapping times ranging from 100 ms to 2700 ms in 200 ms intervals. The plot also includes the mass spectra collected at the trapping time of 50 ms. -- astro-ph.GA

Charge Transfer From Ammonia Neutralizes Propylene Oxide Cations: Implications For The Astrochemistry Of Chiral Molecules
