A direct test of the correlation between elastic parameters and fragility of ten glass formers and their relationship to elastic models of the glass transition.

We present an impulsive stimulated scattering test of the "shoving model" of the glass transition and of the correlation between the fragility index and the ratio of instantaneous elastic moduli of eight supercooled liquids. Samples of triphenyl phosphite, DC704 (tetramethyl tetraphenyl trisiloxane), m-fluoroaniline, Ca(NO(3))(2)4H(2)O, diethyl phthalate… (More)
