Thaddeus, P., J. Mather, J.H. Davis, and G.N. Blair, 1974: Detection of the J=1→0 rotational transition of vibrationally excited silicon monoxide. Astrophys. J., 192, L33-L36, doi:10.1086/181583.
The ν=1, J=1→0 rotational transition of SiO at 43.1 GHz has been detected in the direction of Becklin's star in the Orion Nebula, and in the M-type star W Hya. In Orion two velocity components are observed, one (the stronger) at a radial velocity of 17 km/s, the other at -7 km/s; in W Hya a single line is observed at 39 km/s. In each case a line at the same radial velocity has been observed at 86.2 GHz in the ν=1, J=2→1 transition, so that the presence of vibrationally excited SiO would seem to be ocnfirmed beyond a reasonable doubt. In the ν=1 state, the photon fluxes of the J=2→1 and 1→0 transitions are about equal, suggested saturated masers occupying the same region of space.
