Taken together{,} in excess of 85 unique variants were detected{,} including several new isotopic species and more than 25 new vibrationally excited states of C2S{,} C3S{,} and C4S{,} which have been assigned on the basis of published vibration-rotation interaction constants for C3S{,} or newly calculated ones for C2S and C4S. On the basis of these precise{,} low-frequency measurements{,} several vibrationally exited states of C2S and C3S were subsequently identified in archival millimeter-wave data in the 253-280 GHz frequency range{,} ultimately providing highly accurate catalogs for astronomical searches. As part of this work{,} formation pathways of the two smaller carbon-sulfur chains were investigated using 13C isotopic spectroscopy{,} as was their vibrational excitation. The present study illustrates the utility of microwave spectral taxonomy as a tool for complex mixture analysis{,} and as a powerful and convenient {'}stepping stone{'} to higher frequency measurements in the millimeter and submillimeter bands."}
