Network Analyzer Tests of Equivalent Circuits of Vibrating Polyatomic Molecules

Abstract

To illustrate the use of the equivalent circuits derived in the companion paper for vibrating polyatomic molecules, this paper describes network‐analyzer tests of circuits for three successively more complicated molecules. The first is the symmetrical linear CO₂ molecule; the second is the unsymmetrical linear OCS molecule; and the third is the unsymmetrical nonlinear CH₃CH₂OH molecule. In each case, starting from given constants of the molecular structure, the normal frequencies and modes are measured by means of the equivalent circuit. It is shown that for these cases the analyzer measurements agree satisfactorily with the known normal‐frequency characteristics.
