Davis, J.H., G.N. Blair, H. Van Till, and P. Thaddeus, 1974: Vibrationally excited silicon monoxide in the Orion Nebula. Astrophys. J., 190, L117-L119, doi:10.1086/181520.

A 1°K line has been detected in the center of the molecular cloud in the Orion Nebula which is probably the 129,363.1-MHz, J = 3→2 rotational transition of SiO in its first excited (ν = 1) vibrational state. The LSR radial velocity based on this assignment is 15.3 km/s, which is exactly that of the second strongest of the seven lines at 86.2 GHz recently found by Snyder and Buhl, and attributed by them to maser emission by the ν = 1, J = 2→1 transition of SiO. We have been unable to detect vibrationally excited SiO in any other source at 129 GHz, and a search for the ν = 1, J = 1→0 line of CO has also proved unsuccessful.
