Spectroscopic studies of the OC:HCCH complex are reported using a continuous supersonic slit jet spectrometer with broadband frequency mode-hop free tunable infrared quantum cascade lasers (QCL), centered at 4.4 and 4.6 μm. This Letter includes an extended analysis of the ν 3 CO stretching vibration frequency, and investigation of the ν 3 + ν 91 - ν 91 hot band, the ν 3 + ν 91 and ν 3 + ν 81 combination bands for OC-HCCH. The ground state low frequency bend, ν 91, is determined at 20.48361(20) cm -1. The generated rovibrational data is incorporated with previously determined information and used to generate a four-dimensional compound-model morphed potential with radial correction, giving further insight into the molecular dynamics of this complex. © 2011 Elsevier B.V.
