Beer-Lambert plot at 185 nm (a pen-ray Hg/Ar lamp was used as a light source)

The low uncertainty was due to an excellent correlation in the experimental values, as can be seen in Fig. 1 (Beer-Lambert plot)

The UV spectrum was also measured in the 200–446 nm wavelength range; however, no absorption bands were found, despite using high concentrations of the compound, such as 9.1 × 1017 molecule cm-3
