Rotational and vibrational spectroscopy of a weakly bound hexafluoroisopropanol⋯dinitrogen complex: 14N hyperfine splittings, molecular geometry, and experimental benchmarks

Structure and internal dynamics of hexafluoroisopropanol⋯N 2 were uncovered by rotational spectroscopy, aided by spin statistics analyses and ab initio calculations. The data from rotational and vibrational spectra serve as benchmarks for theory.
