Zur formelmäßigen Berechnung der Zuordnung von schwingungsspektroskopischen Frequenzen

For Analytical Calculation of Assignments of Vibrational Spectroscopic Frequencies Using the normal coordinate treatment we calculate assignments of vibrational spectroscopic frequencies of the systems X₃ ( D _3h) and X₄ ( T d) and partially of the systems XY₄ ( D _4h) and XY₆ ( O _h).
