  1. 1.

    A calculation was performed, confirming the earlier empirical assignments in the IR and Raman spectra of organoarsenic compounds. A set of force coefficients permitting the achievement of extremely satisfactory agreement of the calculated and experimental frequencies in the spectra of the molecules was obtained.

  2. 2.

    There is a characteristic vibration not only with respect to frequency, but also with respect to form for a narrow group of coordinates with predominant participation of Q0 (As=O bond); in the region of 580–640 cm−1 there is a characteristic vibration for a narrow group of coordinates with predominant participation of Q2 (As=C bond); there is no strict characteristic vibration for the As-O bond.

  3. 3.

    The difference of the force coefficients of the As=O bonds in the molecules As(O)(CH3)3 and As(O) ·(OCH3)3 confirms the earlier premise of a different nature of the As=O group in the presence of different surroundings of the As atom.
