The real structure of H3+ is angular

Abstract In the present communication, an attempt to clarify what is the real structure of the pivotal interstellar ion H₃⁺ is conducted. Calculations were performed for three H₃⁺ structures: the “traditional” equilateral triangular and linear ones, as well as an angular structure. Based on the G^θ andS^θ values, it is proposed that the real (most stable) structure for H₃⁺ is angular, and not equilateral triangular as accepted until now.
