Abstract
Ultrasonic relaxation arising from the perturbation of conformational equilibria involving both nitrogen and ring inversion processes have been observed in some piperidine derivatives. Conformational equilibria involving nitrogen inversion have also been investigated for some piperidones, morpholines, and piperazines. In many cases the enthalpy differences and energy barriers opposing the conformational changes in question have been found using a new method of analysis.Keywords
