Khusimol

A review of vetiver counts it among the oil’s most concentrated alcohols and, in Haitian oil, among the molecules responsible for its odour. No share is given here.

The khusimol molecule

A computed 3D conformer , modeled, not a photograph of a molecule. PubChem CID 167519.

PubChem’s computed 3D conformer of khusimol (CID 167519, conformer 00028E5F00000001): the shape a computer model gives the molecule, not an experimental structure and not a picture of a real molecule. Ball and stick: 15 carbon, 1 oxygen; the 24 hydrogen atoms are left out for clarity. The balls are drawn smaller than the atoms’ real reach; a double bond is two sticks, side by side.

In the room

scaled so that one ångström is 4 cm (about 400 million times life size): 18.2 cm tall, 33.9 cm across

Atoms

15 carbon, 1 oxygen · 18 bonds between them

Colours

carbon: ink sepia-2; oxygen: rose highlight; bonds: brass. Colour is a convention here and never carries the meaning alone: the letters on the drawing and this list say which atom is which.
