Known for its accuracy among smell identification tests it is considered to be one of the most reliable (r=.94) and trusted. [1] UPSIT was created by University of Pennsylvania physician and professor of psychology and otorhinolaryngology Richard Doty. Doty is also the director of the University of Pennsylvania’s Smell and Taste Center.
Aromachology is a relatively new science that explores positive feelings induced by odors far from any holistic or healing process. The term covers both natural and synthetic scents. The term aromachology is sometimes mistaken by companies with several other terms such as "essential oils" or "aromatherapy" as marketing phrases.
A fragrance wheel also known as aroma wheel, fragrance circle, perfume wheel or smell wheel, is a circular diagram showing the inferred relationships among olfactory groups based upon similarities and differences in their odor. [1] The groups bordering one another are implied to share common olfactory characteristics.
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...

[31] Odor intensity can be divided into the following categories according to intensity: 0 – no odor 1 – very weak (odor threshold) 2 – weak 3 – distinct 4 – strong 5 – very strong
The vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak non-covalent interactions between its ...
