Abstract
The resonance Raman spectrum of a nickel‐containing species isolated in solid argon is reported and assigned to Ni3. On the basis of isotopic fine structure analysis its geometry is determined to be C2v with an apex angle between 90° and 100°. This structure is postulated to come about as a result of two effects: the high flexibility of Ni3 along the bending coordinate about the linear form and the geometry of available trivacancies within the face centered cubic solid support. The molecular ground state is suggested to be Δu of unknown spin multiplicity. Consequently, it is argued that the molecular lability comes about as a result of the Renner–Teller effect.Keywords
