I haven't double-checked your work, but the formula in Radiance was borrowed from an earlier version of WINDOW. I can try to dig up the paper where their derivation was published, if no one else comes up with it in the next couple of days.

Hello Everyone,
I was after derivations of glass material formulas, defined in Radiance material document. I looked up the online mailing list but couldn't find much.
In case anyone is interested or for future reference I post my findings here in this link; I hope it's correct
Sorry if I am re-sending something that already existed/documented.
Regards,
