<h2>Octane numbers and NIR spectra of gasoline</h2>
<h3>Description</h3>
<p>
A data set with NIR spectra and octane numbers of 60 gasoline samples.
The NIR spectra were measured using diffuse reflectance as log(1/R)
from 900 nm to 1700 nm in 2 nm intervals, giving 401 wavelengths.
Many thanks to John H. Kalivas.
