Detection of C3 in Diffuse Interstellar Clouds

Abstract

The smallest polyatomic carbon chain, C3, has been identified in interstellar clouds (Av ∼1 mag) towards ζ Ophiuchi, 20 Aquilae, and ζ Persei by detection of the origin band in its AΠu −X 1Σ+g electronic transition, near 4052Å. Individual rotational lines were resolved up to J=30 enabling the rotational level column densities and temperature distributions… (More)
