It is impossible to give a single evaporation coefficient for an essential oil, as each oil contains many (often hundreds) of chemicals each with their own coefficient. If I asked you for the evaporation coefficient of Cool Water, the question would be meaningless; it is the same for Essential oils.

The notes of essential oils are a simple way of speaking about the volatility or evaporation rate of a particular essential oil. The top or high note essential oils are usually light and airy. They dissipate quickly into the air and will not linger, typically lasting only 1-2 hours at the most. Essential oils, though all highly volatile, do not all evaporate at the same speed, and this difference in the time taken to evaporate directly affects the length of time the smell of the oil will linger, and the time it will take to be absorbed into the body when applied to the skin. Those oils which take longest to evaporate (i.e., the least volatile) will continue to perfume the skin, or any substance to which they are applied, for many hours and in a few cases even days, while those The Cboe Crude Oil ETF Volatility Index ("Oil VIX", Ticker - OVX) measures the market's expectation of 30-day volatility of crude oil prices by applying the VIX ® methodology to United States Oil Fund, LP (Ticker - USO) options spanning a wide range of strike prices.
