On Extragalactic HNC

C. Henkel, P. Schilke, and R. Mauersberger
reported on
Molecules in External Galaxies – The Detection of CN, C2H, and HNC, and the Tentative detection of HC3N,
Astron. Astrophys. 201, L23–L26 (1988).
The IRAM 30 m telescope was used to detect the J = 1 – 0 transition near 90.7 GHz in emission in the starburst galaxy IC 342.

Soon thereafter,
R. Mauersberger and C. Henkel
reported on
Dense Gas in Nearby Galaxies. IV – The Detection of N2H+, SiO, H13CO+, H13CN, and HN13C,
Astron. Astrophys. 245, 457–466 (1991).
The IRAM 30 m telescope was used to detect the J = 1 – 0 transition near 87.1 GHz in emission in the Seyfert galaxy NGC 253.

F. Costagliola, S. Aalto, K. Sakamoto, S. Martín, R. Beswick, S. Muller, and H.-R. Klöckner
carried out a
High-resolution mm and cm Study of the Obscured LIRG NGC 4418 – A Compact Obscured Nucleus Fed by In-falling Gas ?,
Astron. Astrophys. 565, Art. No. A66 (2013).
Vibrationally excited HNC was detected for the first time with the SMA. the J = 3 – 2 transition of v2 = 1 was detected. The e-component appeared as a weak shoulder to the ground state emission line, whereas the f-component was essentially not overlapped.
