Most of the identified compounds in Estonian chamomile oil have been reported previously; however, 1,2,4-trimethylbenzene and decanoic acid were not mentioned in the literature [1-11].

The fuel library within the standard GT-power software distribution does not comprise of all the species needed to describe LLNL surrogate fuels [15], and hence it was modified to accommodate the following species: cyclopentane, 1-hexene and 1,2,4-trimethylbenzene. The properties for the fluid and vapor objects for GT power were taken from NIST webbook [20].
