What is it about?
Water is everywhere and plays a critical role in biological, chemical, and physical systems. We have shown that rotations of one water molecule can change the rotational frequencies of another. We have observed spectral signatures of previously unseen metastable water complexes, suggesting these complexes have multiple preferred bimolecular geometries.

Why is it important?
Our work directly reveals the presence of previously unseen metastable water complexes with lifetimes of 100 ps or longer. These transient water complexes are previously inaccessible and may help resolve elusive behaviors of water. Our finding also deepens the understanding of water dynamics in the gas phase, and hence is crucial for creating a panorama of the research on water.
