Production of Si(1D2) from Electronically Excited SiH2

摘要

Silicon (1D2) has been detected by atomic laser-induced fluorescence following photoexcitation of cyclosilane into high bending vibrational levels of the A1B1 state. The Si(1D2) into high bending vibrational levels of the A1B1 state. The Si(1D2) + diatomic hydrogen channel appears to open between v2' = 6 and 7, establishing heat of formation (SiH2) = 65.4 + or - 1.6 kcal/mol. SiH2 appears to dissociate preferentially from high rotational levels of the A, v2' > 6 states. Keywords: Photodissociation.
