Spectra of rhodamine

Figure 9.17 Absorption and fluorescence spectra of rhodamine B in methanol (5 X 10 mol 1 ). The curve marked is for the J 2 absorption (process 8 in Figure 9.18) and that marked 5 for process 1.

Grochala, Kudelski, and Bukowska [228] have described the anion-induced charge-transfer enhancement in S E RS and S E RRS spectra of rhodamine 6G on Ag electrode as a function of the electrode potential, upon addition of chloride and citrate anions. In a very recent paper, Brolo et al. [229] have discussed the ratio of the surface-enhanced anti-Stokes scattering to the surface-enhanced Stokes-Raman...

Figure 11.5a shows SHG spectra of rhodamine B (RB) adsorbed at the heptane/water interface. A single major peak assigned to a resonance with the Sq-S i electronic transition of RB is recognized in each spectrum. The peak positions in these spectra are determined by fitting data points to a combination of Lorentzian functions based on the two-state model [60].
