To exploit the photochemical reactivity of THC as a means of detection, we added an additional PD that would capture changes in emission structure post-degradation (C365 region shown in Figure ; 365 nm +/-5nm). The new spectral feature centered at ~365 nm has both the largest relative magnitude and is the most blue-shifted species from the emission spectra arising from flavoring compounds (Figure ). This means that the C365 PD minimizes any artifactual spectral convolution.
