Starting with the Big Bang, this book tells the story of the development of chemistry within our universe to the present day.Topics covered include: the spontaneous formation of the first chemical elements; the formation of higher chemical elements through stellar nucleosynthesis; the rich variety of 'alien' chemistry occurring in large interstellar gas clouds; formation of the solar system and evolution of the Earth; and the physical and chemical structure of today's atmosphere. Simple photochemical models are used to explain a range of phenomena such as the greenhouse effect, the formation of the ozone layer and the self-cleansing properties of the troposphere.Astrochemistry and Atmospheric Chemistry is suitable for undergraduates in chemistry and astrophysics, as well as anyone interested in the topic. This is a must-read for those who wish to understand the role of physical chemistry in the formation and current set-up of the world we live in.
