Asymmetric Choreography in Pairs of Orthogonal Rotors

An asymmetric mechanism for correlated motion occurring in noninteracting pairs of adjacent orthogonal 1,4-bis(carboxyethynyl)bicyclo[1.1.1]pentane (BCP) rotators 1 in the solid state is unraveled and shown to play an important role in understanding the dynamics in the crystalline rotor, Bu4N+[1-]·H2O. Single crystal X-ray diffraction and calculation of rotor-rotor interaction energies combined...

Dynamics of Asymmetric Rotors using Solid Models

Copyright © 2003 by GTSJ Manuscript Received on July 7, 2003 ABSTRACT Asymmetric rotors or shafts with dissimilar moments of area form a special category of rotor dynamics problems. Of specific interest for these rotors is the instability in the region of half critical speed, also called gravity critical speed. General analysis of such rotors is limited to Jeffcott type beam models. This involv...
