Table 1.  Iodine nqcc's in ClCCI (MHz).  Calc = B1LYP/6-311G(df,p).   Calculation was made on re [2] structure.

127I
Xzz - 2251.6 - 2280(40)

  







   








The difference between calculated and experimental nqcc's is 28 MHz (1.24 %).  This difference lies within the uncertainty in the experimental value.

 








 








   








Table 2.  Chlorine nqcc's in ClCCI (MHz).  Calculation was made on re [2] structure. Calc = B1LYP/TZV(3df,2p).  (Ahlrichs' TZV basis for iodine is available here.)
