### Abstract

We present methodology for variational calculation of the 6n-dimensional translation-rotation (TR) eigenstates of assemblies of n H_{2}O@C_{60} moieties coupled by dipole-dipole interactions. We show that the TR Hamiltonian matrix for any n can be constructed from dipole-dipole matrix elements computed for n=2. We present results for linear H_{2}O@C_{60} assemblies. Two classes of eigenstates are revealed. One class comprises excitations of the 111 rotational level of H_{2}O. The lowest-energy 111-derived eigenstate for each assembly exhibits significant dipole ordering and shifts down in energy with the assembly size.
