HNSi; ν1 emission band by high resolution Fourier transform spectroscopy

The emission spectrum of the fundamental vibration-rotation ν1 band (NH stretch) of iminosilicon HNSi has been observed near 2.7μm 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 ?, B, D, 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.

Gas-Phase Chemistry of HSiS- and HSiNH-: Ions Related to Silathioformaldehyde and the Silaazomethine of Formaldehyde

Anions related to silathioformaldehyde (H2Si=Si) and the silaazomethine of formaldehyde (H2Si=NH) have been prepared and studied using flowing afterglow selected ion flow tube techniques.The connectivities of these anions are shown in experimental studies to be - and -.In addition, ab initio computational studies demonstrate that these are the most stable anion isomers.These anions are prepared by both collisionally-induced dissociation and direct source reactions.The anions resulting from the later preparations have been submitted to reaction chemistry studies with CO2, COS, CS2, SO2, O2, and C6F6.Comparisons with earlier studies of HSiO- are made in terms of a simple mechanistic picture.
