Comment on ‘‘Short time dynamics of glass‐forming liquids’’ [J. Chem. Phys. 103, 1152 (1995)]

Roland and Ngai [J. Chem. Phys. 103, 1152 (1995)] challenged the interpretation of short‐time dynamics of glass‐forming liquids in terms of mode coupling theory by suggesting that the usual analysis shows critical singularities even when applied to smooth synthetic data. However, their analysis relies on a nonreproducible fit and overlooks several inconsistencies that in any experimental work would have been interpreted as clearly contradicting mode coupling theory.
