The single chirality of biological molecules in terrestrial biology raises more questions than
certitudes about its origin. The emergence of biological homochirality (BH) and its …

Molecular biology and biochemistry interpret microscopic processes in the living world in
terms of molecular structures and their interactions, which are quantum mechanical by their …

Nitrogen-bearing polycyclic aromatic hydrocarbons (PANHs) are ubiquitous in space. They
are considered precursors to advanced biomolecules identified in meteorites. However, their …

A hybrid quartic force field approach produces the same accuracies as non‐hybrid methods
but for less than one quarter of the computational time. This method utilizes explicitly …

The rule-based search of chemical space can generate an almost infinite number of
molecules, but exploration of known molecules as a function of the minimum number of …

Dust grains play a central role in the physics and chemistry of cosmic environments. They
influence the optical and thermal properties of the medium due to their interaction with stellar …

Urea is a molecule of great interest in chemistry and biology. In particular, it is considered a
key building block in prebiotic chemistry on Earth. The hypothesis of its possible exogenous …

Accurate binding energies of molecules to water clusters are relevant for understanding
intermolecular interactions and various chemical applications. They enter models of …

Simple Summary Organic matter is an integral part of all living things on our planet, but
abiotic (not relating to life) organic matter can be found throughout the Solar System within …

Quantum chemistry can uniquely answer astrochemical questions that no other technique
can provide. Computations can be parallelized, automated, and left to run continuously …
