Question

What are differences between n→π* and π →π* bonding electron transition in Fluorescence? Please answer shorty at your own words. Answer should be to the point.

Expert Solution

Step 1

Absorption spectroscopy of organic compounds is generally based on n→π* and π→π* bonding electron transition.

n→π* bonding electron transition =

This is lone pair non bonding orbital (n) and pi anti bonding orbital (π^*) transition.
Molar absorbtivities of this transition is very low, that is 10 to 100Lmol^-1cm^-1.
The peaks resulted from this transition shift towards shorter wavelength with increase in polarity of the solvent.
