Abstract

Dipole moments and molar Kerr constants at 25° are recorded for 3-chloropropyne, 3-bromopropyne, phenylacetylene, diphenylacetylene, di-(p-chlorophenyl)acetylene, and dimethyl and diethyl acetylenedicarboxylate, as solutes in carbon tetrachloride. Anisotropic polarisabilities (bL = 3.79, bT = bv = 1.26) for the C≡C bond, deduced from literature data, are satisfactorily applicable to 3-chloropropyne, 3-bromopropyne, and phenylacetylene. Observations on the esters can be interpreted in terms of a mixture of non-planar cis- and trans-isomers.
