Circular dichroism data collection

There are many other types of data which can be collected and reported in appropriate circumstances, uv, ord (optical rotatory dispersion), cd (circular dichroism) etc. 

Further important data for an understanding of liquid-crystalline phases of cellulos-cis can be provided by a number of investigations, such as flow behavior, induced circular dichroism, and many more. A collection of literature and details is given in [2]. We have limited ourselves to a discussion of basic chirality and phase behavior. 

Polymers obtained from PEL monomers of different optical purity were characterized as follows (1) for crystalline properties by differential scanning calorimetry (DSC) and wide-angle x-ray diffraction (2) for relative molecular weights by solution viscosity (3) for structure by IR and NMR spectroscopy and (4) for chiroptical properties in solution by optical rotatory dispersion (ORD) and circular dichroism (CO). Molecular weight and melting point data for both the racemic and optically-active PEL polymers are collected in Table I.
