✦ Synopsis


We have carried out a TDQM study of photoinduced desorption in NO/Pt by involving hot electron transfer and allowing different residence times (ZR) on the excited state potential-energy surface. The desorption probabifity (P~) is dependent on ~'g, but it is clear from the results that the substantial P~ can be accounted for by assuming TR is in the range 20-60 fs. The study also accounts for vibrational excitation in the desorbed NO.

Results from a time-dependent quantum-mechanical study of the collinear reaction He+H: +HeH+ +H are reported in the form of reaction probability values as a function of the total energy of the system for different vibrational states of Hz. The resonances are related to flux patterns similar to that
