A Study on the Physical Properties of Saturated Fatty Acids for External Stimulus

The structural changes of molecules on the water surface were measured by displacement currents and $\pi$-A isotherm. By using a theoretical equations we calculated charges($\Delta$Q) and dipole moment( $m_{z}$) of saturated fatty acids( $C_{12}$, $C_{14}$, $C_{16}$). The dynamic behavior of saturated fatty acid monolayers at the air/water interface was investigated using a displacement current-measuring technique coupled with the so called Langmuir film technique and also the dipole moment of the acids was determined.as determined.d.
