Abstract
Molecules in a Langmuir film are wobbling in the time range of nanosec ond. The wobbling motion of beta-DPH HPC assembled as Langmuir films w ere measured by time-resolved fluorescence depolarization method. Usin g ''double cone model'', it was found that the angular range and the v elocity of the motion decreased with increasing of the density of the molecules in the Langmuir films.
