Figure 4
UV–vis spectrum of the title polymorph dissolved in DMSO. The experimental spectrum (red line) is fitted with Gaussian functions for which maxima are indicated. The sum of these Gaussian functions affords the theoretical spectrum (dotted blue line). The visible range of the spectrum is displayed in the inset, using a scale allowing the d–d transitions to be assessed, fitted with two Gaussian functions, giving a maximum at λ = 598 nm. |
