    • MM calculations are of little assistance in this case as the carbon atom types present in squaramides are not parametrized.

    • For solubility reasons, the study was limited to squaramido esters 3. Full details concerning the conformational behavior of squaramides will be published elsewhere.

    • note
    • The value is apparent as it is affected for the dimerization of the Z form, and it reflects not only the rotation around the C-N squaramido bond but also the process of forming and breaking hydrogen bonds.
