The Rich Interstellar Reservoir Of Dinitriles: Detection of Malononitrile and Maleonitrile in TMC-1
While the nitrile group is by far the most prevalent one among interstellar molecules, the existence of interstellar dinitriles (molecules containing two -CN groups) has recently been proven. Here we […]

More Sulphur In TMC-1: Discovery Of The NC3S And HC3S Radicals With The QUIJOTE Line Survey
We present the detection of the free radicals NC3S and HC3S towards TMC-1 with the QUIJOTE line survey. The derived column densities are (1.4±0.2)×1011 for NC3S and (1.5±0.2)×1011 for HC3S.

Laboratory And Astronomical Discovery Of Cyanothioketene, NCCHCS, In The Cold Starless Core TMC-1
We present the detection of cyanothioketene, NCCHCS, in the laboratory and toward TMC-1. This transient species was produced through a discharge of a gas mixture of CH2CHCN and CS2 using […]

CN And CCH Derivatives Of Ethylene And Ethane: Confirmation Of The Detection Of CH3CH2CCH In TMC-1
We present a study of CH3CH2CCH, CH3CH2CN, CH2CHCCH, and CH2CHCN in TMC-1 using the QUIJOTE1 line survey. We confirm the presence of CH3CH2CCH in TMC-1, which was previously reported as […]
