Machine Learning Prediction of the Most Intense Peak of the Absorption Spectra of Organic Molecules

Rubens C. Souza ; Julio C. Duarte ; Ronaldo R. Goldschmidt ; Itamar Borges Jr.

Molecules from the QM-symex database are converted to SMILES (simplified molecular input line entry system) and stored in a new QM-symex-modif dataset with their target properties. The data is processed and used in machine learning models to develop predictive models for photophysical properties.
