GetSpecies(opt)

Parameters

opt

-

(optional) the option speciesnames=t where t is default or original

Description

• 

The GetSpecies command returns a list containing the chemical names known to the ThermophysicalData:-Chemicals package.

• 

These can be used with the ThermophysicalData:-Chemicals:-Property command to get thermodynamic data.

• 

If the speciesnames=original option is provided, then the original names, as defined in the data source McBride et al. 20002, are returned instead of the default names.
