DNA films with psi +/- CD spectra have been investigated. X-ray analysis has shown the sign of the psi spectra to be independent of the secondary structure of DNA. The appearance of the psi spectra is attended by the formation of a characteristic polygonal texture of the cholesteric type in the DNA film.
已对具有ψ±圆二色光谱的DNA薄膜进行了研究。X射线分析表明，ψ光谱的符号与DNA的二级结构无关。ψ光谱的出现伴随着DNA薄膜中胆甾型特征多边形纹理的形成。
