Energies are expressed in kJ/mol, and probabilities in percent; Free energy of $^{1}$C 4 ; Next most populated conformer after $^{4}$C 1 and $^{1}$C 4 ; c Free energy of the next most populated conformer; d Location of the transition state ( θ , φ ); e Free energy of the transition state ; f Population of $^{4}$C 1 (%); g Population of $^{1}$C 4 (%); h Population of the next most populated conformer. When a basin is present, which encompasses many states, all conformers involved are listed.
