We have used a molecular-beam photoionization technique to probe the vibrational-energy distribution of SF/sub 6/ molecules excited by an intense CO/sub 2/ laser at energy fluence close to and below the dissociation threshold. We observe a significant bottleneck at low laser intensities. Even at laser fluences close to the dissociation threshold, most of the molecules remain in the discrete levels, and only a small fraction (approx.10--25%) are excited into the quasi-continuum.
