Abstract: We used an experimental set-up built in Brussels connecting an $Ar^{+}$ pumped, home-made Sa:Ti laser cavity to a commercial high resolution Fourier transform spectrometer Bruker $IFS120HR,^{a}$ to perform ultra sensitive (ICLAS) molecular absorption spectroscopy in the near infrared range in both $^{12}C_{2}HD$ and $^{13}C^{12}CH_{2}$. We also recorded new conventional FT data in Bologna and Brussels. They are being analyzed and the results are gathered with literature information on additional vibrational energy states in both acetylene isotopologues separately. We are first attempting to perform global modeling of the vibrational energy pattern by defining adequate polyad interaction schemes and will then turn on to global vibration-rotation modeling, using a dedicated computer program package developed in $Louvain.^{b}$ We shall report on the latest results.
