Spatial separation of 2-propanol monomer and its ionization-fragmentation pathways

Jia Wang, Lanhai He, Jovana Petrovic +5

The spatial separation of 2-propanol monomer from its clusters in a molecular beam by an electrostatic deflector was demonstrated. Samples of 2-propanol monomer with a purity of 90…

Pure Molecular Beam of Water Dimer

Helen Bieker, Jolijn Onvlee, Melby Johny +5

Spatial separation of water dimer from water monomer and larger water-clusters through the electric deflector is presented. A beam of water dimer with 93 % purity and a rotation…

Spatial separation of pyrrole and pyrrole-water clusters

Melby Johny, Jolijn Onvlee, Thomas Kierspel +3

We demonstrate the spatial separation of pyrrole and pyrrole(H2​O) clusters from the other atomic and molecular species in a supersonically-expanded beam of pyrrole and traces of…

Knife edge skimming for improved separation of molecular species by the deflector

Sebastian Trippel, Melby Johny, Thomas Kierspel +7

A knife edge for shaping a molecular beam is described to improve the spatial separation of the species in a molecular beam by the electrostatic deflector. The spatial separation o…
