Standard enthalpy change of formation (data table)

These tables include heat of formation data gathered from a variety of sources, including the primary and secondary literature, as well as the NIST Chemistry WebBook. Note that the table for Alkanes contains Δ_fH^o values in kcal/mol, and the table for Miscellaneous Compounds and Elements contains these values in kJ/mol.
