Interstellar Molecules
Interstellar molecules are molecules that exist in the space between stars. These molecules are formed through a variety of processes, including gas-phase reactions, surface chemistry on dust grains, and photodissociation of larger molecules. Interstellar molecules play a crucial role in the chemical evolution of the universe, as they are the building blocks for the formation of more complex molecules and ultimately, the formation of planets and life. The study of interstellar molecules involves a range of techniques, including radio and infrared spectroscopy, and has led to the discovery of many new molecules and insights into the physical and chemical conditions of the interstellar medium.
