Odorant shape and vibration likely lead to olfaction satisfaction

A new study lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules. The study demonstrates the feasibility of the theory – first proposed decades ago – that the vibration of an odorant molecule's chemical bonds – the wagging, stretching and rocking of the links between atoms – contributes to our ability to distinguish one smelly thing from another.
