This paper presents a finding of the correlation between the width of a strong diffuse interstellar band at 6196 Å and the excitation temperature of C2 based on high resolution and high signal-to-noise ratio spectra. The excitation temperature was determined from absorption lines of the Phillips 
and Mulliken 
systems.
The width and shape of the narrow 6196 Å DIB profile apparently depend on the C2 temperature, being broader for higher values.
