Intramolecular deformations in organic molecules

Complex organic molecules in organic-poor massive young stellar objects

Context. Massive young stellar objects (MYSOs) with hot cores are classic sources of complex organic molecules. The origins of these molecules in such sources, as well as the smalland large-scale differentiation between nitrogenand oxygen-bearing complex species, are poorly understood. Aims. We aim to use complex molecule abundances toward a chemically less explored class of MYSOs with weak hot...

Characterization of Interstellar Organic Molecules

Understanding the origins of life has been one of the greatest dreams throughout history. It is now known that star-forming regions contain complex organic molecules, known as Polycyclic Aromatic Hydrocarbons (PAHs), each of which has particular infrared spectral characteristics. By understanding which PAH species are found in specific star-forming regions, we can better understand the biochemi...

Polaritonic Chemistry with Organic Molecules

We present an overview of the general concepts of polaritonic chemistry with organic molecules, i.e., the manipulation of chemical structure that can be achieved through strong coupling between confined light modes and organic molecules. Strong coupling and the associated formation of polaritons, hybrid light−matter excitations, lead to energy shifts in such systems that can amount to a large f...

Bonding in Organic Molecules. Atomic-orbital Models

I n previous chapters, we have shown how you can use ball-and-stick models to predict the general arrangements in space of organic molecules. The sticks correspond to chemical bonds, which we represent in structural formulas as lines, or in Lewis struc'tures as pairs of dots denoting shared pairs of electrons. Remembering that electrons and nuclei are charged particles, and that it is electrica...
