A relationship exists between the amount of the ultraviolet (UV) extinction and the relative strength of the very broad structure (VBS) in the 500–600 nm wavelength region (5000–6000 Å) of the interstellar extinction curve. It is based on observations of OB stars distributed along the Milky Way. By examining E(B-V), we found that larger-than-mean values of the UV extinction correspond to larger-than-mean strengths of the VBS and vice versa. This feature is thought to be an emission arising from photoluminescence (PL) of small amorphous carbonaceous grains.
