Abstract
IN a recent communication (NATURE, Jan. 11), Dieke and Holtgreven have given details of a new system of the C2 molecule. The band heads (degraded to the ultra-violet) have long been known from the work of Deslandres and D'Azambuja (vide Kayser's “Handbuch”, vol. 5, p. 234), while in 1916, Raffety (Phil. Mag., vol. 32, p. 546) recorded four of the strongest bands as associated with the Swan bands under his experimental conditions. Vibrational and fine structure analysis have now been made for the first time by Dieke and Holtgreven, making this the third known system of the C2 molecule.
