Linear dichroism ld
NettetThe non-invasive techniques of linear dichroism (LD) and circular dichroism (CD) have contributed significantly to our knowledge of the molecular organization of different complexes and of the pigment systems in entire membranes from a great variety of photosynthetic organisms. It was suspected already in the mid-1970s and the early 1980s, Nettetの試料の巨視的異方性 (linear birefringence: LB, linear dichroism: LD) や、拡散反射に重畳する正反射が CD スペクトルに及ぼす影響について明らかになっていないため、それらを明らかにし、新たにDRCD スペクトルを測定する方法を提案する必要がある。
