The emission spectrum of the fundamental vibration-rotation nu(1) band (NH stretch) of iminosilicon HNSi has been observed near 2.7 microns by high-resolution Fourier transform spectroscopy from a mixture of N2 + SiH4 excited in a radio frequency discharge. This is the first spectroscopic observation of this molecule in the gas phase. Molecular constants sigma, B, D, and H are reported. Calculated microwave transitions which should be helpful for the investigation and the possible identification of HNSi in astrophysical sources are also given.
