Abstract
We report on electric deflection experiments of structural isomers of aminobenzonitrile. They are used as models to study the influence of the asymmetry of a molecule on the molecule-electric field interaction. Experimental deflection profiles are compared to Stark effect calculations. We found increasing deviations from the calculated Stark effect behavior with increasing asymmetry. This deviation is induced by interactions with other particles and is directly related to the chaotic behavior of the rotational motion of asymmetric rotors in a static electric field.
AI evidence extraction
Structured fields below were generated from the paper’s abstract and metadata to make the evidence easier to inspect. Automated extraction may be incomplete or incorrect; verify important details against the original paper.
Main findings
Electric deflection profiles of aminobenzonitrile structural isomers deviated increasingly from Stark effect calculations as molecular asymmetry increased. The deviations were attributed to interactions with other particles and related to chaotic rotational behavior of asymmetric rotors in a static electric field.
Outcomes measured
