摘要: The photolysis of thin layers tert- and iso-butyl nitrite, physisorbed on a transparent insulating MgF2 surface, has been investigated. (1+1′)-Resonance-enhanced multiphoton ionization (REMPI) spectroscopy was used to characterize the desorbed NO. For high-J rotational levels, preference for Π(A″) Λ-doublet small degree alignment is observed. axis found be parallel plane polarization laser perpendicular surface normal, indicating cartwheeling mode desorption. photofragment yield (PHOFRY) spectrum nitrite also reported.
