Non-Boltzmann form

Fukutani et al. [8] also observed NO desorption from on-top species at X = 193 nm. The results are very similar to those obtained by Buntin et al. at X = 532 and 355 nm. The decay of the desorption yield on this surface at X = 532 nm gives a desorption cross section of 1 x 10-22 cm2 [6]. A fit to the TOF spectrum by the non-Boltzmann form gives Tt = 910 K. Rotational energy distributions of... 

The rotational energy distribution of desorbed NO from on-top species on Pt(l 1 1) at A. = 192 nm is observed to have a non-Boltzmann form, as shown in Fig. 14. Furthermore, the population in the two spin-orbit states is substantially inverted, since the population ratio of 2 = 1/2 and 3/2 is 1 2.2 in low J region. For desorption of hep hollow species at = 193 nm, on the other hand, the population ratio...
