.. py:class:: Janafspecie(W, Tlow, Thigh, Tcommon, lowCpCoeffs, highCpCoeffs, P)


   Represents a chemical species using JANAF thermodynamic data.

   This class models the thermodynamic properties of a species based on
   JANAF polynomial coefficients for specific heat capacity and entropy
   over a range of temperatures.
