A broadband tunable single-frequency color center laser optothermal molecular beam spectrometer has been constructed. K components have been resolved for P(18) to R(11) rovibrational transitions in ν1 CH3C≡C–H. The observed transition linewidths are demonstrated to be ≤6 MHz and are determined with a relative precision of ≤10 MHz over the 15-cm-1 frequency segment scanned.
