Explain the solvent effect on electronic spectra for n - transitions. In which solvents are they particularly seen?

N-π* (n to pi star) transitions are electronic transitions that occur in molecules where an electron in a non-bonding (n) orbital transitions to an antibonding (π*) pi star orbital. These transitions are common in molecules with conjugated systems, such as those found in organic compounds with alternating single and double bonds.

The solvent in which a molecule is dissolved can have a significant impact on its electronic spectra, including n-π* transitions. Solvent effects arise due to interactions between the solute molecule and the solvent molecules, which can alter the energy levels of the electronic states involved in the transition. There are mainly two solvent effects that can influence n-π* transitions: _________ __________ ______ _________ _________ _________ _____ __________ ________ ___ __________.
