In methane the distance between the hydrogen atoms is 1.8 angstrom but the combined van der Waals radii of hydrogen are 2.4 angstrom implying steric hindrance. Also in propane the methyl to methyl distance is 2.5 angstrom whereas the combined van der Waals radii are much larger (4 angstrom).
Thermodynamic data is usually presented as a table or chart of function values for one mole of a substance (or in the case of the steam tables, one kg). A thermodynamic datafile is a set of equation parameters from which the numerical data values can be calculated.

The technique was developed by professor Sidney William Benson [1] of the University of Southern California. It is further described in Heat of formation group additivity. Heats of formations are intimately related to bond-dissociation energies and thus are important in understanding chemical structure and reactivity. [2]
