✦ Synopsis

The rotation-vibration spectrum of the weakly bound complex (\mathrm{CO}-\mathrm{Kr}) has been studied in the (2140-\mathrm{cm}^{-1}) region of the CO fundamental band using a long-path ( (84 \mathrm{~m}) ) low-temperature (84 K) static absorption cell and a high-resolution Fourier transform spectrometer. Over 140 lines with (J)-values up to 35 have been assigned to the perpendicular subbands with (K=1 \leftarrow 0) and (0 \leftarrow 1). Their analysis yields information on the rotational and centrifugal distortion parameters for (K=0) and (I) and (v_{\mathrm{cO}}=0) and 1 . The band origin for the complex is (2142.642 \mathrm{~cm}^{-1}), which represents a shift of (-0.630 \mathrm{~cm}^{-1}) from the (\mathrm{CO}) monomer origin. No direct evidence was seen for line splittings due to (\mathrm{Kr}) isotopes. (C 1993 Academic Press, Inc

The HNC molecule was generated by the reaction of translationally hot H atoms with either ClCN or BrCN. The energetically rich HNC products were probed by time-resolved infrared laser absorption spectroscopy. This allowed for the spectroscopic analysis of 16 vibrational bands in the wavelength regio
