What is it about?
The manuscript applies density-functional methods (DFT) as well as molecular dynamics and tight-binding parametrized methods to describe and predict vibrational characteristics of octahedrane. The value of this work to future studies is in its use as a reference system for DFT parametrization — hydrocarbon cages are very important data sets for this purpose, and octahedrane is the most thermodynamically stable (CH)12 hydrocarbon. Further, since there are no other published experimental or theoretical vibrational spectra for octahedrane, our study provides another excellent opportunity to provide accurate vibrational spectra for future experimental and theoretical work on other hydrocarbons with unique shapes and symmetries, which we feel will be of great interest.
