Scientific paper

High-resolution, high-S/N spectra are used to study a system of three diffuse interstellar bands (DIBs) near 6200 A; the intensity ratios of the three bands are noted to change from one line-of-sight to another, thereby suggesting that there is a different carrier for each. It appears that intensity-ratio changes are not accompanied by profile-shape changes. A relation between the extinction law and the behavior of this DIBs system is suggested.
