28. Comparison of spectra of the original solution and of the redissolved material showed that the precipitation process did not cause significant changes in the composition of the reaction mixture, nor did the precipitation itself promote any reactions.
29. 2 and also because and it is brightly colored (orange), so that one can see where the compound had been deposited. The carbene (35 mg) was placed in the supercritical cell and then flushed out through the back-pressure regulator and into the collection vessel, and it was found that >90% of the carbene could be collected.
30. 3) was insufficiently high to obtain conclusive evidence for the presence of a metal-hydride resonance. Although Cp*Ir(CO)(H)Et could be precipitated and satisfactorily redissolved for our IR experiments, it appeared to decompose during our NMR procedure and no satisfactory NMR data were obtained.

33. 2, because the vibrational coupling between the two Ir-H bonds is relatively small and the separation between the symmetric and antisymmetric vibrational modes is less than their line widths (see, e.g.: Duckett, S. B.; Haddleton, D. M.; Jackson, S. A.; Perutz, R. N.; Poliakoff, M.; Upmacis, R. K. Organometallics 1988, 7, 1526).

35. 2, are quite soluble in scXe, and under the conditions of our experiments, the concentrations of all solutions were substantially below saturation.
36. -1 resolution spectrum. However, the precision of the peak-picking algorithms is much higher, at least 10 times higher than the nominal resolution. The reproducibility of the separation between well-resolved peaks, such as those in our experiments, would be expected to be even higher (Mills, I. M. Personal communication, 1995). Thus, we have used the separation of the bands rather than their absolute wavenumbers, because the absolute values show some slight dependence on the precise pressure and temperature of the scXe, while the separations are insensitive to the small differences which inevitably occur between experiments.
37. 2, one would expect a small but significant shift from the v(C-O) band of Cp*Ir(CO)(H)Et.
