We discuss the bound states of weakly bound van der Waals trimers within the framework of hyperspherical coordinates. The wave function is expanded in terms of hyperspherical harmonics, which form a complete basis set in the angular variables. The resulting set of coupled second-order differential equations in the hyperradius is solved exactly. Our method gives a value for the zero-point energy of H{sup +}{sub 3} which is in excellent agreement with previous calculations. For (H{sub 2}){sub 3} and Ne{sub 3}, however, our results show some discrepancy with earlier work.
