These are the quantum yields for O(1D) production from O3 photodissociation [ala Lori Perliski]

for wavelength < 305 qy(O1d)=1.0

for wavelength > 305 and < 320

qy(O1d)= a0(t)+a1(t)*x+a2(t)*x*x+a3(t)*x*x*x+a4(t)*x**4
 +a5(t)*x**5+a6(t)*x**6

 where
 x=(wavelength-305) and t=(298-temperature)

 and

 a0=.94932-1.7039e-4*t+1.4072e-6*t**2
 a1=-2.4052e-2+1.0479e-3*t-1.0655e-5*t**2
 a2=1.8771e-2-3.6401e-4*t-1.8587e-5*t**2
 a3=-1.454e-2-4.7787e-5*t-8.1277e+6*t**2
 a4=2.3287e-3+1.9891e-5*t-1.1801e-6*t**2
 a5=-1.4471e-4-1.7188e-6*t+7.2661e-8*t**2
 a6=3.183e-6+4.6209e-8*t-1.6266e-9*t**2


if qy(O1d) < 0.02 then qy(o1d)=0.0


for wavelength > 320 qy(O1d)=0.0


and of course, qy(O3p)=1.-qy(O1d)
