Research And Development Intern WebThe CMC of SANPAs was determined using a solvatochromic Nile Red dye (9-diethylamino-5-benzo-[a]-phenoxazinone, Thermo Fisher, Waltham, MA, USA). 16 The mechanism here is that Nile Red is mostly non-fluorescent in water or other polar solvents but undergoes fluorescence enhancement in nonpolar environments, with a large blue shift for both …

WebWe show that while the solvatochromic shift in the VEE is minimal (0.1 eV blue shift) and its polarization component is only 0.03 eV, the effect of the solvent on the VDE is quite large (3.85 eV). We also show by accurate calculations on the solvatochromic shift of the VDE that polarization accounts for ∼0.23 eV and therefore cannot be neglected. WebThis clearly indicates that the QM/EFP-molecular dynamics can be a viable way of obtaining an anharmonic infrared spectrum that provides information on solvatochromic frequency shifts and fluctuations, solute-solvent interaction-induced dephasing, and anharmonic coupling effects on vibrational spectra of aqueous solutions.
