光是一种能,而化学变化每每伴有能的变化,讨论这两者间的相互关系,是属于光化学(photo-chemistry)的范围。在黑夜里,常见荒塜间有星星之火,这由于黄磷的自动氧化作用(Autoxida-tion),可为因化学反应而产生光能的最好例子。举凡因化学反应而发光的作用,吾人均称为「化学发光作用」Chemilumines-cence),或简称化光作用。绿柳成阴,万紫千红,一切植物成长的复杂反应,无有不藉助于日光。这种作用,可说明光能对于化学反应的影响;也就是光化学真正的领域。因光能引起的化学反应,称为光化反应(Pho-to chemica Ireaction)。光化反应中最基本的定
Light is a kind of energy, and chemical changes are often accompanied by changes in energy, to discuss the relationship between the two is part of the scope of the photo-chemistry (photo-chemistry). In the darkness, there are stars and stars between common famine, which is the best example of the light energy produced by chemical reactions due to the auto-oxidation of yellow phosphorus. The effect of all due to chemical reaction and luminescence, we are all called “chemiluminescence” Chemilumines-cence), or simply actinic effect. Green Liu Chengyin, colorful, all the complex response to plant growth, both without the help of sunlight. This effect can explain the impact of light on the chemical reaction; that is, the real field of photochemistry. Because of light-induced chemical reactions, known as the photochemical reaction (Pho-to chemica Ireaction). Photochemical reaction in the most basic set
