Abstract

A new NMR method for structural verification and ¹¹B resonance assignment in (car)borane clusters is presented, based on the measurement of ¹¹B residual quadrupolar couplings (RQCs) in a stretched polystyrene (PS) gel. The method was applied to ortho-carborane (B₁₀C₂H₁₂), a derivative thereof with reduced symmetry, meta-carborane and decaborane (B₁₀H₁₄).
