Mid-infrared spectra (4000-400 cm-1) of mixtures of HCl with ethyl-d5, n-propyl, isopropyl-d7, or tert-butyl chloride, dissolved in liquefied argon (95-117 K) and liquefied krypton (122-148 K) have been investigated.In all cases the formation of a 1:1 van der Walls molecule between HCl and the alkyl chloride was observed.At gigher concentrations, a new absorption band, due to a 1:2 complex (RCl)*(HCl)2 was found.The association enthalpy in liquefied argon was determined to be -9.8 +/- 0.6 kJ mol-1 for C2D5Cl*HCl, -10.0 +/- 0.5 kJ mol-1 for gauche-n-C3H7Cl*HCl and -10.8 +/- 0.5 kJ mol-1 for iso-C3D7Cl*HCl.The ΔH0 for the C2D5Cl*HCl species in liquefied krypton was determined to be -9.4 +/- 0.5 kJ mol-1.For the formation of the 1:2 complex from the 1:1 complex and hydrogen chloride, the ΔH0 was determined to be -3.7 +/- 0.4 kJ mol-1 for the ethyl-d5 chloride complex and -4.5 +/- 0.3 kJ mol-1 for the isopropyl-d7 chloride complex.
