万物生长靠太阳,太阳创造了整个生物界。自然界的化学过程相当大的一部分是光化学过程。人类自古以来对光化学过程就相当熟悉,如染料在光照下会褪色,植物靠太阳光可以生长等等,但是对这一过程却一直不能理解,甚至到本世纪中期还不十分理解。由于近代物理学的发展,特别是量子化学的发展,对于化学键的本质有了较深入的认识,光化学才在现代化学的概念上重新发展起来,成为认识世界、改造世界的一个新领域。六十年代以来,国际上对于物质的光化学过程的
Everything grows by the sun, the sun has created the entire biological world. A considerable part of the chemical processes in nature is photochemical processes. Humans have become familiar with photochemical processes since ancient times. For example, dyes can fade under light and plants can grow by sunlight. However, this process has not been understood until even by the middle of this century. Due to the development of modern physics, especially the development of quantum chemistry, the nature of chemical bonds has been deeply understood. Photochemistry has only been re-developed in the concept of modern chemistry and has become a new field of understanding and transforming the world. Since the 1960s, the international photochemical process of matter
