QTAIM based descriptors for the classification of acrylates

open access: yesTheoretical Chemistry Accounts, 2023
AbstractAcrylates are used in cosmetics, orthopedics, paints, coatings, adhesives, textiles, and biomedical applications such as contact lenses and bone cements. However, some acrylates are mutagenic and the aim of this article is to explain the mutagenicity in terms of the atomic population redistribution in the molecule using two new descriptors ...
