| Summary:
This lecture course is an introduction to molecular astrophysics (also known as astrochemistry).
The spectroscopic and continuum observations of simple inorganic and complex organic molecules in space are at the forefront of observational astronomy. Powerful new facilities such as the Atacama Large Millimeter/submillimeter Array and the James Webb Space Telescope have enabled us to probe the molecular composition of the Universe from the Big Bang to local interstellar space, and from the distant past to the present. The wealth of diagnostic data is driving extensive laboratory and theoretical studies aimed at extracting key information about the physics and chemistry of space from these data. Our understanding of the life cycle of matter in the Universe is also intertwined with such a fundamental question as the origin of life.
In this course, you will learn how molecules can be detected in a variety of interstellar environments, from the interstellar medium to planetary atmospheres, and how they are formed and destroyed there. You will learn about the basic spectroscopic properties of molecules and solids, how molecular lines and solid-state bands are used to study the underlying physical and chemical properties of the matter. The major processes of molecule formation and destruction in space, and the interplay between the gas-phase and surface reactions will be discussed from both experimental and theoretical perspectives. You will learn about the formation of the first elements after the Big Bang and the main chemical processes in the early Universe. You will also learn about the formation of other elements in stars, and what happens to these elements after they are ejected into the interstellar space at the end of the star's life. Finally, you will learn about exoplanets, atmospheres, habitability, and the origin of life.
