An error in Table I11 listed the ratio of the intensity of the Raman band at 811 cm-l to that at 1098 cm-1 in the poly I-poly C complex as 1.5. This value should have been 1.6. The average maximum value of this ratio for the three helices which can be reversibly ordered in the A form (poly I-poly C,

## Abstract The Raman spectra of the double helical complexes of poly C–poly G and poly I–poly C at neutral p^H^ are presented and compared with the spectra of the constituent homopolymers. When a completely double‐helical structure is formed in solution a strong sharp band at 810–814 cm^βˆ’1^ appea
