The absorption and circular dichroism (CD) spectra of allophycocyanin II in the trimer and monomer (dissociated) forms were resolved into four and two components, respectively. The short-wavelength region of the visible spectra was approximated by a chimera of Lorentzian- and Gaussian-shaped bands having a bandwidth of ca. 65 nm. The rest of the bands have a pure Gaussian form. The characteristic 652-nm band in the absorption spectrum (656 nm in the CD spectrum) is shown to arise from exciton interaction between two fluorescent phycocyanobilin chromophores.
别藻蓝蛋白II三聚体和单体（解离）形式的吸收光谱和圆二色光谱（CD）分别被解析为四个和两个组分。可见光谱的短波长区域由带宽约为65 nm的洛伦兹型和高斯型带的嵌合体近似。其余的带具有纯高斯形式。吸收光谱中特征性的652 nm带（CD光谱中为656 nm）显示是由两个荧光藻蓝胆素发色团之间的激子相互作用引起的。
