The optical properties of phenazine, 5,10-dihydrophenazine, 1: 1 phenazhydrin, and 3: 1 phenazhydrin have been investigated, and ir, uv, and diffuse reflectance spectra are reported. The ir data indicate that the structures of the phenazhydrins resemble those of the parent compounds. The uv spectrum of 5,10-dihydrophenazine has a Λmax at 350 nm, which is not in agreement with a previously reported value of 325 nm. Absorption spectra of the reduced phenazine were also obtained via diffuse reflectance and a subtraction technique. Absorption in the visible region which is not present in the solution spectra is observed in the diffuse reflectance spectra of the phenazhydrins. The optical spectra of the four related compounds are collectively presented and discussed.

Diffuse Reflectance Spectra

Diffuse reflectance spectrum as a noninvasive method has been widely used to study the optical properties of cutaneous skin tissue. In this work, we optimized an eight-layered optical model of basal cell carcinoma skin tissue to study its optical properties. Based on the model, the diffuse reflectance spectra were reconstructed in visible wavelength range by Monte Carlo methods. After different blood contents were added to the optical model, the contribution of blood to diffuese reflectance spectra was investigated theoretically. The ratios of basal cell carcinoma skin and normal skin tissue were also calculated for both experimental result and rebuilt results to testify the theoretical reasonability of the model and methods.
