Abstract
The octane number of a product is directly determined from its near infrared (NIR) absorption spectrum in the wave number spectral range of from 6667 to 3840 centimeter .sup.-1. A number (n) of frequencies is selected within this range, and the (n) absorbance values are correlated with the octane number by using a multivariate regression analysis.
