To encourage the recognition of "polarity of molecule, " one of the most important concepts in chemistry, measurements of dipole moments are to be introduced into the student practice for chemistry majors. We have constructed a compact, easy-handling, and sturdy system for obtaining the dipole moment of the molecule of a liquid sample from experimental data for students to use in the practice in general and physical chemistry. Measuring cells for versatile measurements for a wide variety of dielectric constants ranging from water to non-polar solvents were developed. Computer programs for computer-aided operations of the apparatuses, data acquisitions with a personal computer through a GP-IB interface, and calculations with input data to obtain dipole moments were newly developed. The system are checked and invented by using actually in a practice course for 3rd year students.

为了提高学生对“分子极性“这一重要化学概念的认识，化学专业的学生将在实验中引入偶极矩的测量。我们已经构建了一个紧凑，易于操作，坚固的系统，用于从实验数据中获得液体样品的分子的偶极矩，供学生在普通和物理化学的实践中使用。开发了用于测量从水到非极性溶剂的各种介电常数的多功能测量单元。新开发了用于设备的计算机辅助操作的计算机程序、通过GP-IB接口用个人计算机进行的数据采集以及用输入数据进行计算以获得偶极矩。该系统在三年级学生的实践课中得到了实际应用和验证。
