Novel approach for dipole moment laboratory experiments. A physical chemistry laboratory experiment

Abstract

The determination of the dipole moment of polar molecules in solution has been a standard experiment in many physical chemistry laboratories, and is described in many laboratory texts.1'2 The experiment can be done by bridge methods or by heterodyne-beat approach.3 In both cases the cost of equipment used, while relatively large, was not considered as an important factor. Nowdays however, due to inflation and Department budget cuts this is not so any more. We propose a method of direct counting which has the advantage of low cost, simplicity, and precision; moreover its functioning is more easily understood by the students than that of the classical approach.

Characterization of dimethylsulfoxide/glycerol mixtures: a binary solvent system for the study of “friction-dependent” chemical reactivity

“…The apparatus was calibrated using a series of organic solvents and the calibration curve deviates only slightly from the Thompson equation for the ideal circuit. 39 Refractive indices, n D 20 , were measured at 20 AE 0.2 1C using an Abbe refractometer from Atago (model 1T).…”

Solvation Dynamics of a Radical Ion Pair in Micro‐Heterogeneous Binary Solvents: A Semi‐Quantitative Study Utilizing MARY Line‐Broadening Experiments

“…Static dielectric constants, ε s , were measured using a home‐built oscillating circuit described elsewhere 26. Using a calibration method against pure solvents, the static dielectric constants of the various mixtures were fitted with parametric equations.…”

Experimental observation of preferential solvation on a radical ion pair using MARY spectroscopy

“…Static dielectric constants were measured using a home-built swing circuit described elsewhere. 25 Using a calibration method against pure solvents, the static dielectric constants of the various mixtures were fitted with parametric equations and were used for calculation.…”
