Normal Coordinate Calculation

New values have been obtained for the intensities of the three fundamentals of sulphur dioxide. They are A1 = 317 ± 8, A2 = 376±20, A3 = 2560 ± 70, in units of 1010 sec.−1 cm.−1 at S.T.P. The normal coordinate calculation gives values for the bond moment derivatives and for the molecular dipole moment which demonstrate that the amount of charge moving in all three vibrations is greater than that inferred from the equilibrium charge distribution. The involvement of unshared electrons is suggested.
