Abstract
Differences in the kinetics of polymorphic transformation of crystallographic phases of different parity n- alkanes: tricosane C23H48 and tetracosane C24H50 were studied by FTIR spectroscopy. It has been established that a first-order structural phase transition occurs with a change in the symmetry type of the initial orthorhombic or triclinic sub-cells to hexagonal ones through the formation of a number of intermediate rotator phases (RI, RII, RV) depending on the symmetry of the molecules.
