DFT-Machine Learning Approach for Accurate Prediction of pKa

open access: yes, 2021
In this study, we propose a novel method of pKa prediction in a diverse set of acids, which combines density functional theory (DFT) method with machine learning (ML) methods.

Conical Intersections in Organic Molecules: Benchmarking Mixed-Reference Spin–Flip Time-Dependent DFT (MRSF-TD-DFT) vs Spin–Flip TD-DFT

open access: yes, 2019
The mixed-reference spin–flip time-dependent density functional theory (MRSF-TD-DFT) method eliminates the erroneous spin contamination of the SF-TD-DFT methodology, while retaining the conceptual and practical simplicity of the latter.

EXAFS, DFT, light-induced nucleobase binding, and cytotoxicity of the photoactive complex cis-[Ru(bpy)2(CO)Cl]+ [PDF]

open access: yes, 2010
The aqueous photochemistry of cis-[Ru(bpy)2(CO)Cl]+ (1) was investigated at 310 K and under visible light (white) irradiation by NMR and ESI-HR-MS. Complex 1 releases a Cl ligand, coordinates a solvent molecule, and forms the complex cis-[Ru(bpy)2(CO ...

A conceptual DFT approach towards analysing toxicity

open access: yesJournal of Chemical Sciences, 2005
The applicability of DFT -based descriptors for the development of toxicological structure - activity relationships is assessed. Emphasis in the present study is on the quality of DFT -based descrip- tors for the development of toxicological QSARs and, more specifically, on the potential of the electrophili - city concept in predicting toxicity of ...

Computational molecular characterization of the flavonoid rutin

open access: yesChemistry Central Journal, 2010
In this work, we make use of a model chemistry within Density Functional Theory (DFT) recently presented, which is called M05-2X, to calculate the molecular structure of the flavonoid Rutin, as well as to predict the infrared (IR) and ultraviolet (UV-Vis)
