How do molecules rotate in a solvent? Answering this question is a complicated task since the rotation is perturbed by a large number of surrounding atoms, requiring large-scale computer simulations which are sometimes infeasible. Now, scientists have proven that angulons -- quasiparticles he proposed two years ago -- do in fact form when a molecule is immersed in superfluid helium. This offers a quick and simple description for rotation of molecules in solvents.
