Vinylidene is the lowest
energy decomposition channel. A loose 50% restricted rotor transition state
was used to estimate k(inf). The k(o) value is the expression from the shock
tube study of Ren et al.(2012), who observed no significant pressure falloff
from second order behavior. Lindemann falloff parameters were
used(Fc=1). High values for k(inf), k(o), and Fc were needed to fit the
absence of pressure dependence but are difficult to justify theoretically.
Relative efficiencies are GRIMech values. |
