Abstract

Abstract: In this paper,we have obtained molecular Eckart barrier in thermal unimolecular reaction system,of formaldehyde,calculated the tunneling correction factor for this channel under several different temperatures,which proved the fact that tunneling effect under lower temperature is evident,and studied the interaction of molecular and radical channels,and calculated k_uni(i),E_a(i) for each channel when tunneling effect was Considered for molecular channel but not existed in radical channel.The calculated results are in agreement with those from the experiments.

Key words: Eckart barrier, Formaldehyde, Tunneling correction factor, Interaction of channels
