## Abstract Linear response theory in the decorrelation or randomβphase approximation is used to calculate the absorption and CD spectra of model helical polymers, including singleβstranded polyadenylic acid. The method, which makes use of infinite polymer selection rules for the linear response te

## Abstract The CD spectra of a number of helical complexes formed by purine monomers and complementary pyrimidine polyribonucleotides have been observed over the range 200β400 nm. Each of these spectra is quite similar to that of the corresponding polymerβpolymer helix. The spectra are evidently d
## Abstract The CD spectra of films of the lithium salt of __E. coli__ and calf thymus DNA, and alternating dβAT : AT were measured as a function of relative humidity. Films of the ammonium acetate salt of DNA were also measured. The ammonium films yield the previously reported Aβform CD spectra. A
## Abstract Circular dichroism (CD) spectra of poly(dA), poly(dT), poly(dA)Β·poly(dT), and poly[d(AβT)]Β·poly[d(TβA)] have been measured as a function of temperature. From these data difference spectra have been calculated by subtracting the spectrum measured at low temperature from the spectra measu
Working within the restrictions of a model, we have calculated the circular dichroism of the dinucleoside phosphates ApA, CpC, ApC, and CpA for various conformations. Comparing the calculated curves with those measured in aqueous solution we find agreement for ( 1 ) ApA as a right-handed helix with
