Secret of Scent Lies in Molecular Vibrations

Molecular vibrations, rather than molecular shape, give substances their distinct smell according to a new study by UCL scientists.

In a study designed to find out how smell is written into a molecule’s structure, scientists tested whether changing how a molecule vibrates on a nano-scale changes its smell.

Molecules are made of atoms connected by bonds. The arrangement of bonds and atoms defines the vibration of the molecule. Chemists can therefore identify molecules by their vibrations, using a spectroscope. (more…)
