Abstract:
By using the dielectric relaxation method, we studied molecular dynamics of α-tetralone. Our purpose was to reveal the molecular origin of secondary processes observed for this very simple-structured molecule. To this end, we carried out dielectric measurements at both ambient and elevated pressure of neat α-tetralone and in mixture with oligostyrene. By means of both experimental observations and theoretical calculations, we proved that one of the secondary relaxations has the intramolecular origin, while the other is undoubtedly the intermolecular process called Johari-Goldstein relaxation characteristic of the glassy state.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
Conformations of Ethane and Propane
Staggered conformation is a low energy and more stable conformation with the C-H bonds on the front carbon placed at 60°dihedral angles relative to the C-H bonds on the back carbon, leading to a reduced torsional strain. In staggered ethane, the...
