Abstract :We have investigated the temperature disperison of die­ lectric constants and dielectric loss factors of some dipolar liquids with the microwave interference method at 3.2 Mc/s);. cm • insert ignore into journalissuearticles values(9375 The imaginary part s` of the complex dielectric constant of bromoform, aniline, o-chloro-aniline and bromocyclohexane exibit maximums at eertain temperatures. Using the measured maximum value of s` and the eorresponding value bf s` it has been possible to calculate £ca the optical dielectric constant, . and it has been found that for bromoform, aniline and o-ehloro- aniline it is larger than the square of the index of refraction. Obviouslly, this is due to the atomic polarization. In the case of bromocyclohexane SCO is equal to n^ meaning that there is no atomic polarization in the molecules of this liquid. It has also been possible to determine the atomic polariza­ tion of dipolar liquids. Finally, I wish to express my gratitudes to Prof. R. Nasuh- oğlu for his suggestion and guldence at this work.
