The gauche effect in fluorinated compounds is predominantly explained by a combination of hyperconjugative electron delocalization and electrostatic interactions.

The analysis

The retrieved papers consistently support the claim that the gauche effect (particularly in organofluorine systems) is governed by stereoelectronic forces, specifically hyperconjugation and electrostatic interactions.
