Abstract Fourier transform infrared spectroscopy has been used to investigate the IR spectra of the XNCO (X = Cl, Br, I, CN), the XSCN (X = Cl, Br, I) and the NCNCS vapor molecules from 4800 to 400 cm −1 . Vibrational frequencies have been determined for each normal mode of vibration in each molecule in this region.

The reaction of NCO(X2Π) radicals with C2H2 was investigated under pseudo-first-order conditions at 20 and 100 Torr total pressure as a function of temperature in the range 298–981 K. NCO radicals were generated by excimer laser photolysis of CINCO/Ar mixtures and were detected by laser-induced fluorescence. In the temperature range 296–597 K the measured rate constants exhibit a positive temperature

The microwave spectra of three further isotopic species of chlorine isocyanate (35Cl15N12C16O, 37Cl15N12C16O, 35Cl14N13C16O) have been measured. From them we have obtained rotational constants, centrifugal distortion constants, and nuclearquadrupolecoupling constants. The data are combined with earlier data (1) to confirm the planarity of the molecule, and to give a full substitution structure as
