Work

One of chemistry's most important missions is to discern what molecules look like - how molecules are arranged in a structure. A method Peter Debye developed in 1912 to determine how electrical charges are distributed in a molecule became important in the mapping of molecular structures. At the same time, X-ray radiation was becoming an important tool for mapping crystalline structures, but Peter Debye also developed methods for using both X-rays and electron beams to map molecular structures in gases, for example.
