1.Study of vibrational spectra, dipole moments, and Kerr constants show the molecules of the trialkyl arsenates (CH3O)3AsO and (C2H5O)3AsO to each exist as two rotational isomers, the equilibrium system in each case containing these isomers in essentially equal proportions, under ordinary conditions.2.In one of these isomers the three RO groups are arranged in something close to a cis configuration with respect to the As=O bond [C3v(C3) symmetry]; in the other, one RO group is in a trans position (Cs symmetry). This last isomer is more polar and less favored energetically. |
