A total of twenty-eight coal samples were collected from the Northern Great Plains and Rocky Mountain provinces. Two hundred and thirty-eight coal samples and 261 data printouts were provided to other agencies involved in coal research. Qualitative and quantitative infrared data were collected for 55 channel samples. The effects of different crystallinities in standard minerals on this type of analysis was investigated. The sixteen column samples of Herrin (No. 6) coal collected from three localities in Illinois were described in terms of their lithotype content. Methods of cluster analysis are discussed. Measurements of aliphatic C-H content by FTIR have been correlated to the plastic properties and liquefaction behavior of a set of coals and vitrinite concentrates obtained from the Lower Kittanning seam. Certain types of structural information about coal can be obtained from physical constitution analysis. The details of two such methods are discussed. The surface areas and micropore volumes of coals varying in rank from anthracite to lignite were measured from CO/sub 2/ uptake at 298 K. CO/sub 2/ area is high for anthracitic coal. Swelling of macerals in water was studied by comparing its sorption using pycnometric and gravimetric techniques. Macerals show significant swelling in water.
