Comments: The authors have utilized an acetylene gas sample to assess the performance of a newly constructed cavity ringdown 
laser absorption (CRDS) spectrometer at the Arkansas Center for Laser Applications and Science (ArCLAS). During this assessment 
process, four overtone combination bands were observed for the 13C2H2 species, three of which have not been previously reported 
in the literature.
