AbstractIn 1942 Gerhard Herzberg demonstrated the existence of l-type doubling in a number of bending fundamental levels of linear molecules. He attributed the doubling partly to asymmetric-top effects and partly to Coriolis interactions with the stretching modes, but Harald Nielsen and Wave Shaffer claimed that it is a purely Coriolis effect. The dispute, which was due mainly to errors in theoretical calculations, lasted for several years. This paper presents a summary of the controversy, based on published papers and letters exchanged between the main participants. PACS No.: 33.10En 1942, Gerhard Herzberg a démontré l'existence d'un dédoublement de type l dans un certain nombre de fondamentaux de molécules linéaires. Il attribua ce dédoublement en partie à des effets de rotor asymétrique et en partie à des interactions de Coriolis avec les modes d'étirement, mais Harald Nielsen et Wave Shaffer soutînrent que l'effet était purement Coriolis. Ce désaccord, largement dû à des erreurs de calcul théorique, dura plusieurs années. Ce papier présente un résumé de la controverse, basé sur des publications scientifiques et sur des lettres échangées entre les principaux participants. [Traduit par la Rédaction]
