Selector for Structural Isomers of Neutral Molecules
We have selected and spatially separated the two conformers of 3-aminophenol (C(6)H(7)NO) present in a molecular beam. Analogous to the separation of ions based on their mass-to-charge ratios in a quadrupole mass filter, the neutral conformers are separated based on their different mass-to-dipole-moment ratios in an ac electric quadrupole selector. …
