BACL + HV = PRODUCTS
! Biacetyl absorption cross sections from Plum et al (1983).
! Unit quantum yield assumed for low wavelength photolysis.
! High wavelength quantum yield adjusted to give same effective photolysis
! rates for EC in period of EC-900's as reported by Plum et al (1983) for
! that chamber, using the following model:
! Quantum yields between 0.328 and 0.350 assumed to be constant at 1.000 nm.
! Quantum yields above 0.350 assumed to decrease linearlly to zero at 0.421 nm.
