Here we identify 24 molecules of interest for prebiotic chemistry in the ISM. Three of them had been identified in our In Section 2, we describe the six screening principles and the resulting dataset of potential interstellar prebiotic molecules. This screening process, combined with our prior methodology , led to the identification of 24 likely interstellar molecules, five of which have been previously detected. Section 3 details the quantum chemical methods used to optimize geometries, calculate energies, and determine spectroscopic properties of the identified molecules (considering all conformers). The energetic, structural, and spectroscopic results for the 19 molecules and their conformers are presented in Section 4. .
