So a conjugated system is a system of connected p orbitals or alternating single and multiple bonds.
I know that conventionally, we count the number of adjacent parallel p orbitals or alternating single-double bonds to see which molecule is "more conjugated" or not. However, when considering the following molecules: I cannot seem to find out which molecule is "more" conjugated or not.
Is there a way to calculate the degree of conjugation? And in this case, would the rhodamine B be the most conjugated compound in the list?
