Abstract
The phase characterisation and morphologies of forms I and II of terephthalic acid are presented. The structural nature of the II → I polymorphic phase transition has been explored and form II shown to be more stable at room temperature and pressure. A new mechanism is proposed for the apparent stability of multiply twinned samples of form I.Keywords
