One man's passion for perfume leads him to explore one of the most intriguing scientific mysteries: What makes one molecule smell of garlic while another smells of rose? In this witty, engrossing, and wildly original volume, author Luca Turin explores the two competing theories of smell. Is scent determined by molecular shape or molecular vibrations? Turin describes in fascinating detail the science, the evidence, and the often contentious debate—from the beginnings of organic chemistry to the present day—and pays homage to the scientists who went before. With its uniquely accessible and captivating approach to science via art, The Secret of Scent will appeal to anyone who has ever wondered about the most mysterious of the five senses.
...some very phenolic compounds are used as replacemants in cases, such as the soaps, where vanillin cannot be used because it rapidly turns chocolate-brown (查看原文)
Natural vanilla extract contains lots of phenolic notes, and smells a bit like a fresh exotic-fibre carpet or smoky, wet tea leaves. This is desirable, because pure vanillin is a little too clean all by itself, and needs a bit of phenolic raunch to perform at its best in perfume. Indeed, when Jacques Guerlain used vanillin in fragrances, he always choose a somewhat impure grade which smelled nicer (the firm of De Laire sold it to ihim for more than the pure stuff). He then mixed, say, ten parts of this stuff to one of the expensive vanilla absolute to make it both cheap and rich. (查看原文)

后半部分主要在讲Luca Turin对分子振动理论的研究，夹杂一些分子振动理论发展史之类的东西。这部分有些枯燥了，其实看他的TED就能有个大概了解。偏学术的一本书，有一定专业性，至少需要高中化学知识吧。 对于普通爱好者来说，并不是很好的参考书之选，即使里面有些部分介绍了香水行业一些鲜为人知的生产过程。
