Mechanism of Unimolecular Bifurcate Reactions

In this Paper, we haue first established the mechanism of Unimolecular Bifurcate Reactions （UBRs） and pointed out:
（1） UBRs hae the features of unimolecular reactions according to the variation of total reactive rate Vs the total pressure of reachve systems:
（2） UBRs have rival mechanism, their ratio of reactive ratio is decided by UBRs’ modes and the concentration of M.
The UBRs in very impotant for us to know reactive laws and reveal new reactive mechanisms
