COMMENTS: Laser photolysis (308 nm) of formaldehyde and absorption measurements behind shock waves

The temperature dependence of the extinction coefficient α (in cm2/mol) (base e) of the Q(9)/P(2) line of the A 2A ← X 2A band of HCO was obtained:

log α = 6.57 - 1.39×10-3 T + 3.16×10-7 T2 - 4.08×10-11 T3

The calculated extinction coefficients have been converted to absorption cross sections (conversion factor 1.66×10-24)
