Although the definition of dispersion term in SAPT somewhat exaggerates the magnitude of the dispersion effect, the SAPT and its variant DFT-SAPT are quite popular and widely employed in literatures in exploring the nature of intermolecular interactions. The ratio between SAPT dispersion term and electrostatics term (d/e ratio) is even more useful in practice, which has been extensively employed to classify a wide variety of molecular complexes. Therefore, we believe it is quite valuable to design a special form of sobEDA method to maximally reproduce the d/e ratio of SAPT so that the result can be compared with SAPT analysis, and this form may also be utilized as an inexpensive substitute for SAPT. To this aim, we defined sobEDAw, which decomposes intermolecular interaction energy as follows
