引言一千多年来,化学一直被认作是一门结构复杂的、难以预测的科学。为改进它的那部分难以预测的性质所作之努力,首先是通过“电子理论”的成功而奏效的。电子理论主要是由象Fry. Steieglitz. Lucao、Lapworth和Sidgwick这样的有机化学家创建的,并由Robinrsn和Ingold使它趋于完善,后来又由其他的化学家发展了它。在电子理论中,分子 Introduction For more than a thousand years, chemistry has always been regarded as a complex and unpredictable science. Efforts to improve the unpredictability of that part of it are primarily through the success of “electronic theory.” The theory of electronics was created mainly by organic chemists like Fry. Steieglitz. Lucao, Lapworth and Sidgwick, which were perfected by Robinrsn and Ingold and later developed by other chemists. In electronic theory, a molecule
