APFIVE Solvent Effects on UV-Vis Spectra
When analyzing the solubility of organic compounds in different solvents, a chemist observes a bathochromic shift (red shift) in the UV-Vis spectrum when changing from a nonpolar to polar solvent. What does this spectral change indicate about the electronic transitions and solubility interactions?
A
Promotion of n→σ* transitions over π→π* transitions
B
Stabilization of the excited state by solvent-solute dipole interactions
C
Increased energy gap between HOMO and LUMO orbitals
D
Destabilization of the ground state by increased hydrogen bonding
