Numerous studies have been conducted to elucidate the complex relationship between the shape of an odorous molecule and its perceived smell character, and fragrance chemists have proposed structure models for the smells of amber, sandalwood, and camphor, among others.
A study by Leslie B. Vosshall and Andreas Keller, published in Nature Neuroscience in 2004, tested several key predictions of the competing vibration theory and found no experimental support for it. The data were described by Vosshall as "consistent with the shape theory," although she added that "they don't prove the shape theory."

Famous quotes containing the word support:
“The purpose of punishment is to improve those who do the punishing—that is the final recourse of those who support punishment.”
—Friedrich Nietzsche (1844–1900)
“But look what we have built ... low-income projects that become worse centers of delinquency, vandalism and general social hopelessness than the slums they were supposed to replace.... Cultural centers that are unable to support a good bookstore. Civic centers that are avoided by everyone but bums.... Promenades that go from no place to nowhere and have no promenaders. Expressways that eviscerate great cities. This is not the rebuilding of cities. This is the sacking of cities.”
—Jane Jacobs (b. 1916)
“‘Tis not enough to help the feeble up,
But to support him after.”
—William Shakespeare (1564–1616)
