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 $T_\text{rot}=0.8\pm0.2$ K, whereas the temperature of the deflected, pure-pyrrole(H $_2$ O) part of the molecular beam corresponds to $T_\text{rot}\approx0.4$ K.
