Spatial separation of pyrrole and pyrrole-water clusters

Abstract

We demonstrate the spatial separation of pyrrole and pyrrole(H${}_2$O) clusters from the other atomic and molecular species in a supersonically-expanded beam of pyrrole and traces of water seeded in high-pressure helium gas. The experimental results are quantitatively supported by simulations. The obtained pyrrole(H${}_2$O) cluster beam has a purity of ~100 %. The extracted rotational temperature of pyrrole and pyrrole(H${}_2$O) from the original supersonic expansion is $T_{\text{rot}}=0.8\pm 0.2$ K, whereas the temperature of the deflected, pure-pyrrole(H${}_2$O) part of the molecular beam corresponds to $T_{\text{rot}}\approx 0.4$ K.
