Abstract
A pump probe femtosecond optical Kerr effect experiment in smectic A p hases of liquid crystals (LC) was performed to select and study the ro tation of the LC molecules around their long axis. A temporal analysis of the signal allowed us to distinguish individual motions from colle ctive motions and to assign some contributions to some particular mole cular groups.
