Photochemistry is the study of the interactions between atoms, small molecules, and light (or electromagnetic radiation). This book collects recent research in the field from around the world. An introductory chapter looks at the interdisciplinary nature of chemical engineering research. Some specific topics covered in later chapters are the photochemistry and applications of benzoindoles and piridoindoles, 2+2 cycloaddition on furan derivatives, photochemistry in ionic liquids, and photochemistry of tetrazole derivatives in cryogenic rare gas matrices. Other subjects explored include hydrogen bonding effects on the photochemistry of chromophores in solution, photochemical generation of silicon-centered radicals and their reactions, and photochemical processes at the air-water interface of atmospheric droplets.
