Abstract
We report in the present paper the circular dichroism spectra of poly(X) at different pH and temperature values. The spectra are characteristic of three stable forms of poly(x) in the pH range of protonation of xanthosine. An electrostatic barrier is proposed to account for the hysteresis and metastability observed in a certain pH range. Some results on oligo(X) at basic pH are also presented. Poly(X) at basic pH is investigated also by hydrodynamic techniques.
摘要
我们在本文中报告了聚（X）在不同pH值和温度下的圆二色光谱。这些光谱是黄苷质子化pH范围内聚（x）三种稳定形式的特征。提出了一个静电势垒来解释在特定pH范围内观察到的滞后现象和亚稳定性。还给出了碱性pH下寡聚（X）的一些结果。碱性pH下的聚（X）也通过流体动力学技术进行了研究。
