Nasa polynomial list for different species

WitrynaThermodynamic data for a range of species can be obtained from the NASA ThermoBuild tool. Using the web interface, an input file can be obtained for a set of species. This input file should then be modified so that the first line reads " thermo nasa9 ", as in the following example: http://akrmys.com/thermNASA/NASApolynomial.pdf
