A series of proton acceptor molecules has been studied in order to determine their mode of interaction with hydrogen chloride as a proton donor molecule as indicated by spectral changes measured using low temperature isolation in an argon matrix.

Interactions were studied with compounds of the type:
$$\begin{gathered} CH_2 = CH - (CH_2 )_n - X\,\,\,\,\,\,\,\,\,\,\,n = 0,1\,and\,2 \hfill \\ CH_3 - CH_2 - X\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,X = CH_3 ,Cl,Br\,and\,C \equiv N \hfill \\ Cl - (CH_2 )_n - C \equiv N \hfill \\ \end{gathered} $$
Weak Van der Waals interactions were measured for CH3-CH2-CH3. Moderate strength hydrogen bonded complexes associated with σ and π electrons were measured in other cases. Correlations for bifunctional molecules suggested that π-bonded forms were preferred to σ-bonded forms. In corresponding mixtures of monofunctional compounds σ and π complexes were simultaneously formed.
