Where these spectra were present, the content was compared to the reported spectra in the original sources.
The reported spectra are accumulations of ten scans, from which the similarly recorded, corresponding solvent spectrum was subtracted.
All reported spectra were corrected for buffer effects, dilution factors, and any wavelength-dependent response for the fluorometer.
The X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectra of the sample showing ∼15% weight loss were compared with the reported spectra of boehmite.
All reported spectra were recorded at a 90° take-off angle relative to the substrate with a VG ESCALAB 220iXL spectrometer using the monochromatized Al Kα radiation (1486.6 eV).
All reported spectra of the exposure time were set to 5 s, and signal was accumulated two times in a range of 500 (approximately 2,000 cm-1).
Furthermore, the second absorption peak at 620 nm is not consistent with reported spectra for gold-coated gold-sulfide nanocolloids, found to be near 790 nm [4].
The chemical structures of the known compounds were determined based on 1H- and 13C-NMR analyses and confirmed by comparison with reported spectra as norartocarpetin (3) [7], artocarpanone (4) [8], liquiritigenin (5) [9], steppogenin (6) [7], and dihydromorin (7) [10] (Fig. 1).
A 1mm path length cuvette was employed, with reported spectra being the average of four scans taken at scan rates of 20 nm/min.
The reported spectra are the average of five scans.
