Free-induction decay line shape for

Figure 5. The proton free-induction decay line shape for H2Os3(CO)i0. The points in the center of the spectrum where no line was drawn are caused partly by probe impurities.

Figure 7. Free-induction decay line shapes for H4Os4(CO)i2 near 100°K and room temperature. The lack of complete symmetry in the line shape may be caused by a probe impurity signal located slightly to the left of the spectra s...

Figure 8. Free-induction decay line shapes for H4Ru4(CO)i2 near 120°K and room temperature. The sharp peak located slightly left of the center in the room-temperature spectrum (and the asymmetry in the lower temperature spectrum) is caused partially by probe impurities.
