    • -1 typically correspond to couplings of low energy modes. One must be wary of structures which yield only very small imaginary frequencies since this suggests a very low energy transition structure which may not correspond to the particular reaction of interest [7b,20-22].

    • note
    • Atomic charges can neither be measured nor calculated unambiguously and it is not possible to say which method provides the "better" atomic charges. However, the shortcomings of the Mulliken population analysis charges are well known. In general, Mulliken charges have a greater tendency to vary than electrostatic charges or natural charges.
