Abstract:

Obtaining the dipole moment in solvents is a classic college-level physical chemistry experiment. The data processing is somehow tedious despite the relatively simple operations. The basic formulas are usually expressed under Gaussian units and this causes difficulties for students who are only familiar with the International System of Units (SI units) with chemistry background. Here we discuss units conversions within the scope of the experiment and emphasize the derivation of the coefficients in the final equation. This may improve both understandings and data processing of the experiment.

Key words: Dipole moment, Solution method, Gaussian units, SI units
