Abstract (from CDS):

This paper presents a finding of the correlation between the width of a strong diffuse interstellar band at 6196Å 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 A¹Π_u-X¹Σ⁺_g and Mulliken D¹Σ⁺_u-X¹Σ⁺_g systems. The width and shape of the narrow 6196Å DIB profile apparently depend on the C₂ temperature, being broader for higher values.
