Abstract

We used the NIST MIM diode TuFIR spectrometer in third order operation to derive center line frequencies, pressure shifts and self-broadening parameters of the J=43-42, J =44-43, J=56-55 and J=68-67 K-multiplets of the ¹Σ⁺_g ground state of CH₃C¹⁴N up to K=10. Improved rotational molecular constants have been determined. The J and K-dependences of pressure shifts and self-broadening parameters are compared with theory.
