PURPOSE:To measure the rotation frequency of molecules by putting the liquid molecules to be measured into an AC magnetic field, rotating synchronously the molecules and measuring the relation between the extent of the movement of an electric charge and the frequency of the synchronous rotation. CONSTITUTION:When the liquid molecules are put into the AC electric field, the polarized molecules rotate synchronously with the frequency applied thereto by trying to orient in the direction of the magnetic field. The AC signal of the same frequency as a synchronous rotation frequency (f) is observed when the potential difference generated in the direction of the electric field is measured. The peak voltage of the AC signal by the potential difference depends on the frequency when the measuring frequency is low. The peak voltage is linear in parallel with the axis of abscissa when V>v and said voltage has dependency on (f) when V<v if the angular speed by the synchronous rotation of the molecules is designated as V, the angular speed of the rotation by thermal motion as (v) and if the generated potential difference taken at the axis of ordinate in logarithm and the (f) taken at the axis of abscissa are plotted. V=v is obtd. when both straight lines are extended and the point of intersection is determined. The rotation frequency of the molecules by the thermal motion thereof is thus obtd. |
