The kinetics of the first-order solid-state structural transition in monodisperse n-alkanes samples of even tetracosane C 24 H 50 was studied by FTIR spectroscopy. The existence of many irregular conformers in solid phases of tetracosane, the concentration of which reaches a maximum when approaching the melting temperature, has been demonstrated. The existence of these defective molecules promotes transitions between different rotator phases in the solid state.
