Water exists as two nuclear‐spin isomers, para and ortho, determined by the overall spin of
its two hydrogen nuclei. For isolated water molecules, the conversion between these …

Like dihydrogen, water exists as two spin isomers, ortho and para, with the nuclear magnetic
moments of the hydrogen atoms either parallel or antiparallel. The ratio of the two spin …

We demonstrate the spatial separation of the prototypical indole (H 2 O) clusters from the
various species present in the supersonic expansion of mixtures of indole and water. The …

Clusters are agglomerates of several similar atoms or molecules [1, 2]. These objects show
size and composition dependent properties, which can not be explained by the well-known …

The electric dipole moments of (H 2 O) n DCl (n= 3–9) clusters have been measured by the
beam-deflection method. Reflecting the (dynamical) charge distribution within the system …

Spatial separation of water dimers from water monomers and larger water clusters through
the electric deflector is presented. A beam of water dimers with 93% purity and a rotational …

Quantum differences of ortho/para H 2 O spin-isomers are considered as a key factor that
determines water property taking into account the ortho/para conversion and the …

Recent phenomenological studies have drawn attention to an appealing effect, observed for
the first time in 1893, today known as water-bridge. The phenomenon has been ascribed to …

Magnetic focusing of a molecular beam formed from a rotationally cooled supersonic jet of
H2O seeded in argon is shown to yield water vapor highly enriched in the ortho-H2O …

Large molecules have complex potential-energy surfaces with many local minima. They
exhibit multiple stereo-isomers, even at very low temperatures. In this paper we discuss the …
