The vibrational relaxation of laser excited O/sub 3/(001) by H/sub 2/O and D/sub 2/O has been studied over the temperature range 295--473 /sup 0/K. The CO/sub 2/ laser-induced chemiluminescent reaction of NO+O/sub 3/(001) was utilized to monitor the decay rate of vibrationally excited ozone. The relaxation probability for both water isotopes has a strong inverse temperature dependence, with D/sub 2/O being four times more efficient than H/sub 2/O. The results are discussed in terms of a metastable complex model for energy transfer.
