Complexes between HC1 and proton acceptors in gas and low temperature argon matrices

FT-IR spectra of mixtures of HC1 and various proton acceptors have been recorded in the gas phase and the enhancement gradient of theP(1) HC1 band with pressure of added gas measured. Bands arising from other collisions to form complexes with longer lifetimes were also measured in the gas and matrix phases. The two kinds of interactions are correlated with proton affinity and dipole moment of added gas.
