Disclosed are compositions comprising one or more undecamantanes. Specifically disclosed are compositions comprising 25 to 100 weight percent of one or more undecamantanes. Also disclosed are novel processes for the separation and isolation of undecamantane components into recoverable fractions from a feedstock containing at least a higher diamondoid component which contains one or more undecamantane components.
