Abstract
In this work, a recently developed analytical theory describing dendrite tips growing in undercooled melts in the absence of convection is tested against experimental data of succinonitrile (SCN) and Si. It is shown as a result that the recently found shape function describes the region of the dendrite tip to some distance from its vertex well.
