The fundamental energetic parameters (intercepts and slopes of straight lines approximating energetic levels) of solvatochromic betaines generated by deprotonation of 2-(4-hydroxystyryl)-3H-indolium salts were determined from solvatochromic data in one-component solvents. It was demonstrated that the solvatochromism of the investigated dyes can be described by the VBHB (vinylogous amide–betaine–hydrogen-bonded
