WebApr 30, 2024 · A method is presented for the direct computation of hydrocarbon strain energies using computational group equivalents. Parameters are provided at several high levels of electronic structure theory: W1BD, G-4, CBS-APNO, CBS-QB3, and M062X/6-31+G(2df,p).

If the overall p-value from the ANOVA table is less than some significance level, then we have sufficient evidence to say that at least one of the means of the groups is different from the others.

The problem of pairwise additivity is completely avoided in the Lifshitz theory, where the molecular structure is ignored and the bodies are treated as continuous media. The forces between the bodies are now derived in terms of their bulk properties, such as dielectric constant and refractive index, which already contain all the necessary information from the original molecular structure. WebThen, pairwise additivity at the level of NP-NP interactions will need to be tested and multibody corrections made, which will be particularly essential for understanding the self-assembly phenomena. Testing the results of such simulations is increasingly made possible by experimental advances such as liquid-cell electron microscopy.
