Methylation analysis was run by the method of Hakomori ( ), followed by hydrolysis with trifluoracetic acid, sodium borohydride reduction, and acetylation. 6LC was performed on a Hewlett-Packard 5970, used as an inlet for a mass spectrometer. Molecular weight was determined on a Sephacryl S-500 column (2.6 x 70 cm), using deionized water as solvent, upward flow, 2.75 ml/min, and detection by refractive index monitor. Model R-401 (Waters Associates). 

An HPLC system, equipped with a Waters solvent delivery system (M-45), two PLgel 20 p,m Mixed-A columns (300 x 7.5 mm) with 20 p,m guard column (50 x 7.5 mm) (Polymer Laboratories, Amherst, MA) and a refractive index detector (model 2410) (Waters, Milford, MA), can be used to study the molecular size and size distribution (e.g. molecular weight and weight distribution) of starch. 

The shape of the vibration-rotation bands in infrared absorption and Raman scattering experiments on diatomic molecules dissolved in a host fluid have been used to determine2,15 the autocorrelation functions unit vector pointing along the molecular axis and P2(x) is the Legendre polynomial of index 2. These correlation functions measure the rate of rotational reorientation of the molecule in the host fluid. The observed temperature- and density-dependence of these functions yields a great deal of information about reorientation in solids, liquids, and gases. These correlation functions have been successfully evaluated on the basis of molecular models.15... 

Such behavior has been interpreted in terms of a molecular model proposed by Brochard-Wyart and de Gennes [143] and further refined [145,146]. The first version of these models considers a solid surface bearing a few end grafted polymer chains, with a surface density, G, below the onset of the mushroom regime gAT<1, with N the polymerization index of the anchored chains). The melt chains have a polymerization index P. Both N and P are assumed to be much larger than Ne, the average number of monomers needed to form an entanglement. Thus the... 

It follows with (18)-(21) that the units for the quantities are Cm" V "mole i.e. those of an nth-order polarizability per mole. Therefore, we refer to as an nth-order molar polarizability of the constituent J. These quantities have to be calculated on the basis of a specific molecular model and appropriate local field corrections have to be taken into account. To simplify the notation, we will drop the index J in the following. A summation according to (99) is implied if the system consists of more than one constituent. 

The second appendix, by Dr. Donald B. Boyd, is an updated compendium of software for molecular modeling, computational chemistry, de novo molecular design, quantitative structure-property relationships, synthesis planning, and other facets of computers helping molecular science. This is one of the most current and most complete compilations anywhere. Appendix 2 provides addresses, telephone numbers, and electronic mailing addresses of suppliers of software. Combined with the subject index of this volume, it is possible to... 

Multidimensional Database. A relational database in which multiple general types of data are stored, indexed, and cross-referenced, for use by several different groups. In chemistry, an example would be a database containing reactions, 2D structures, perhaps generic structures or libraries, and 3D models. Such a database would be used by synthetic, chemical informatic, and molecular modeling scientists. A data warehouse is often a multidimensional database, whereas a data mart is usually single-dimensional.

The principle of minimizing the total exposed molecular surface area Sj parameter is a rough but practical index. Better than the manual manipulation of approximate molecular models this criterion can be a powerful tool for revealing the 3-D mimetism between several molecules. An example to illustrate the...
