k_inf = 5.40E+11 T^0.45 exp(-3600 cal/mol /RT) cm3/mol s

F_cent = (1-0.719) exp(-T/103) + 0.719 exp(-T/1291) + exp(-4160/T)

Third-body efficiencies:

N2                    1.0 
H2     Enhanced by    2.0 
H2O    Enhanced by    6.0 
CH4    Enhanced by    2.0 
CO     Enhanced by    1.5 
CO2    Enhanced by    2.0 
C2H6   Enhanced by    3.0 

SOURCE:

The expression for k_inf was estimated by analogy to reaction
74 H + C2H4 (+M)  -> C2H5 (+M)
with a 4 kcal/mol barrier, according to the calculations of Melius (1992).

k_o and F_cent for N2 are calculated by the method of Troe (1977):
delta-E(0 K) = 4.0 kcal/mol
delta-H(0 K) = -31.0 kcal/mol
<delta E> = 0.30 kcal/mol
The Lennard-Jones parameters: sigma (CH2OH-N2) = 3.72 A, epsilon = 183 K
I+/I = 3.1 (for Waage-Rabinovitch correction)
v = 3640, 3000, 3000, 1460, 1330, 1180, 1050, 900, 420 cm^(-1)
