Jon D.Trudeau, Joe L.Schwartz, and Thomas C. Famar*: Ab Initio Calculations and Experimental Measurement of the Deuterium Quadrupole Coupling Constant in Na2PD03. Page 9788. Due to an error in a unit conversion, values of the activation energies are incorrect. All values of the activation energy of reorientation (E, or V) which are reported in units of kJ must be multiplied by 17.506 to be correct. The temperature in Table I under run 2 should read 253.6, not 523.6. Figure 3 in the text is incorrect and should be replaced by the one given below:

Figure 3. A plot of In (TJ vs inverse temperature (in kelvin) for the high-frequency line of run 2. The solid line is calculated using eq 5 and the following parameters: T~ = 1.6275 X s, V = 21.53 kJ/mol, and T. = 66.4 K. The dashed line is calculated using eq 5 and the following parameters: io = 1.6486 X lO-"s, E, = 38.98 kJ/mol, and T. = 0.00
