摘要
以總阻抗電橋(impedance bridge) 測定四碘化錫之四氯化碳稀薄溶液之介電常數(dielectric constants)，以計算四碘化錫之偶極矩(dipole moment)。全部實驗包括:(1)溶劑四氯化碳之精製，(2)四碘化錫之綜合及精製，(3)樣品溶液之配製又密度測定，(4)電容之測定及介電常數之計算及(5)偶極矩之計算等。計算結果，四碘化錫之偶極矩與零值極為接近，其分子結構應屬非極性。

Dielectric behavior of tin tetraiodide was investigated by the senior author by determining the dielectric constants of its carbon tetrachloride solutions by use of a Q-meter last year. In order to obtain more accurate results. a very precision equipment, impedance bridge, was applied to investigate it again. The experiment consists of 1. Purification of carbon tetrachloride; 2. Synthesis and purification of tin tetraiodide ; 3. Preparation of sample solutions; 4. Capacitance measurements; 5. Dipole moment calculation. The calculated result of dipole moment of SnI_4, is so small that the structure of its molecule is predicted to be non-polar.
