We report on the detection of hydromagnesium isocyanide, HMgNC, in the laboratory and in the carbon-rich evolved star IRC+10216. The J = 1–0 and J = 2–1 lines were observed in our microwave laboratory equipment in Valladolid with a spectral accuracy of 3 KHz. The hyperfine structure produced by the nitrogen atom was resolved for both transitions. The derived rotational constants from the laboratory data are B0 = 5481.4333(6) MHz, D0 = 2.90(8) KHz, and eQq(N) = −2.200(2) MHz. The predicted…

Context. About 40 cyanide compounds have been detected in the interstellar medium, but only 3 examples of organic isocyanide compounds were observed in this medium. Ethyl isocyanide is one of the

Alkaline and Alkaline-earth Cyanoacetylides: A Combined Theoretical and Rotational Spectroscopic Investigation.

The theoretical calculations predict that the linear isomer with formula MCCCN (M= Li, Na, Mg and Ca) is the most stable one for the four metallic cyanoacetylides investigated by combined spectroscopy measurements and theoretical calculations.

Structure and Spectroscopic Properties of Hydrocalcium Isocyanide Isomers: Plausible Astronomical Ca-bearing Molecules

Discovery of two new magnesium-bearing species in IRC+10216: MgC3N and MgC4H.

The synthesis of these magnesium cyanides and acetylides in IRC +10216 can be explained in terms of a two-step process initiated by the radiative association of Mg+ with large cyanopolyynes and polyynes followed by the dissociative recombination of the ionic complexes.
