Plot of energies of various HS-rotamers for all four computationally analyzed HS-syn-B18H21 isomers. Torsion angles were defined as positive in the B(1)-B(2)-B(3)-B(4) direction, between atoms B(2)-B(1)-S(1)-H(S) for isomer 1, B(6)-B(2)-S(2)-H(S) for the experimentally unobtained isomer 2, B(2)-B(3)-S(3)-H(S) for 3, and B(1)-B(4)-S(4)-H(S) for 4.
