The concept of Resonance‐Assisted‐Hydrogen‐Bond (RAHB) is well‐establisted in chemisty. Herein, the nature of RAHB effect have been unveiled for a new family of ethyl N ‐salicylideneglycinate dyes differing in the donor–acceptor properties. The result of combined experimental and theoretical research reveals the nature of RAHB and a direct relationship between the magnitude of RAHB and the strength of intramolecular O−CH⋅⋅⋅N bond, and, consequently, its influence on enol—keto equilibria and further on the photoluminescence and thermochromic properties.
