The new linear molecule Ag−C=C−Cl has been detected andfully characterized by means of rotational spectroscopy. It was synthesized bylaser ablation of a silver rod in the presence of a gaseous sample containing alow concentration of CCl4 in argon, cooled to a rotational temperatureapproaching ∼1−3 K through supersonic expansion, and analyzed by chirpedpulse,Fourier transform microwave spectroscopy. Six isotopologues wereinvestigated, and for each the spectroscopic constants B0, DJ and χaa(Cl) weredetermined. The B0 values were interpreted to give the following bond lengths:r(Ag−C) = 2.015(14) Å and r(C−Cl) = 1.635(6) Å, with r(C=C) = 1.2219 Åassumed from an ab initio calculation at the CCSD(T)/aug-cc-pV5Z level oftheory. The Cu analogue Cu−C=C−Cl was similarly identified andcharacterized.
