  text: Understanding the behavior of molecules interacting with superfluid helium
    represents a formidable challenge and, in general, requires approaches relying
    on large-scale numerical simulations. Here we demonstrate that experimental data
    collected over the last 20 years provide evidence that molecules immersed in superfluid
    helium form recently-predicted angulon quasiparticles [Phys. Rev. Lett. 114, 203001
    (2015)]. Most importantly, casting the many-body problem in terms of angulons
    amounts to a drastic simplification and yields effective molecular moments of
    inertia as straightforward analytic solutions of a simple microscopic Hamiltonian.
    The outcome of the angulon theory is in good agreement with experiment for a broad
    range of molecular impurities, from heavy to medium-mass to light species. These
    results pave the way to understanding molecular rotation in liquid and crystalline
    phases in terms of the angulon quasiparticle.
