Abstract
The helical pyrene arrangement on duplex RNA has been evident from the computer simulations that gave the circular dichroism (CD) bands being well consistent with the experimentally observed CD. The pyrene-arrays exhibit the strong excimer fluorescence whose intensity is dependent on the nucleotide sequences and contexts of duplex RNA.
摘要
计算机模拟显示，双链RNA上的螺旋芘排列很明显，其产生的圆二色性（CD）谱带与实验观察到的CD非常一致。芘阵列表现出强烈的准分子荧光，其强度取决于双链RNA的核苷酸序列和环境。
