    • 38 In the present study low-frequency vibrational features sensitive to methylidyne deuteration are not observed, but it is possible that the methylidyne rocking mode, like λ(W≡C-H), is very weak in the Raman spectra.

    • -1 feature than does Cl-W≡C bending in that calculated H/D shifts are much smaller. The calculated shifts (Table 2) for the Cl-W≡C bend (which could alternatively be described as the methylidyne rocking mode of footnote 37) are so large as to confirm that this mode has not been experimentally located.

    • Because ffr is neglected, the PED is completely described by the single quantity plotted in Figure 7. That is, %R plus 5r in each of the stretching modes is equal to 100, and the sum of %R (and also of %r) over the two stretching modes is equal to 100. The PED for the A bending mode is 100% X because no other e-symmetry modes are considered.

    • One striking feature of these data is that M≡N bond distances are approximately 0.05 A shorter than M≡O bond distances for a given force constant. This systematic effect violates the basic assumption of a row-row bond-distance/force-constant correlation.
