The function d = f(τ) is smallest for τ = 90-100° and largest for τ = 0°; the corresponding bond distance variation amounts to 13 pm or 6%. The height of the torsional cis-barrier is estimated from the enthalpy of formation of gaseous S7 as equal to or smaller than 24 kJ/mol.en540 Chemie und zugeordnete Wissenschaftenelemental sulfursulfur ringssulfur-sulfur bondstorsional barrierbond distancesArticle1865-7117
