CN (3,0) red system features in interstellar translucent clouds.

Abstract (from CDS):

We report observations of four weak absorption lines of the interstellar CN A2Π-X2Σ+ (3,0) band: R1(0) 6951.8Å, RQ21(0) 6927.3Å, R2(1)+RQ1(1) 6926.7Å, QR12(1)+Q1(1) 6953.6Å, and show that they provide reasonable information on column densities in sightlines towards early-type stars. The (3,0) band is always very weak and thus the saturation effect is negligible, which is particularly useful for the sightlines where the near UV-range CN bands are very strong, i.e. saturated.
