✦ Synopsis

Argon matrix infrared spectra of the complexes formed between acetohydroxamic acid (CH 3 CONHOH) and hydrogen halides (HF, HCl) have been recorded. The experimental results indicate formation of a strong binary complex in which the hydrogen halide molecule acts as a proton donor towards the carbonyl group of acetohydroxamic acid. The H -X stretches and several perturbed CH 3 CONHOH vibrations were identified for the two HX complexes; for the HF complex the two librational HF modes were also observed.
