Abstract

Abstract: Hydrogen-bonded T complexes C2H2--HX have been formed by codeposition of C2H2 and HX in excess argon at I5 K and by vacuum-UV photolysis of vinyl halides. The strength of the hydrogen bond, as measured by the displacement of the HX vibrational fundamental below the isolated HX value, decreases in the series HF, HCI, and HBr as expected. Similar complexes made from di-and trichloroethylenes give slightly higher H-CI ...
