Abstract
This invention is a method comprising preparing a sample by coating a thin film of a precursor material, which is free of fluorescent probe molecules onto a substrate and subjecting the precursor material to conditions to attempt to cause cure of the precursor to an organic, aromatic, polymer having a dielectric constant of less than 3.0, exposing the sample to radiation having a wavelength in the range of 200 to 500 nm, detecting a resulting emission of radiation, and comparing the emission to the emission for a known cured, non-oxidized standard for the polymer.
