QSPR = Quantitative Structure Property Relationship developed at NIST/TRC based on computed 3-dimensional structures
Structure-based = The program uses locally stored 3-dimensional structures to determine the symmetry number. This symmetry number includes the contributions from the molecule, as a whole, and internal rotations. Symmetries of structural elements are consistent with those of the groups used in estimation of the intrinsic entropies. The symmetry number is included in the TDE text output.
