A brief critique of the Adam-Gibbs entropy model

Research output: Contribution to journalJournal articleResearchpeer-review


This paper critically discusses the entropy model proposed by Adam and Gibbs in 1965 for the dramatic temperature dependence of glass-forming liquids' average relaxation time, which is one of the most influential models during the last four decades. We discuss the Adam-Gibbs model's theoretical bases as well as its reported experimental model confirmations; in the process of doing this a number of problems with the model are identified
