| Description |
This report is an attempt to understand the short-range structural features, to determine the
relationship(s) between the aryl/alkyl carbon ratio, and to determine the size of the average
polycyclic aromatic unit in Ledo coal from Makum coalfield, Assam, India. An X-ray scattering
analysis of the average polycyclic aromatic unit in the coal indicates that the aromatic fraction in
this coal is 74% with the aliphatic fraction correspondingly estimated to be 26%. The average
carbon atom has 2.3 nearest carbon atom neighbours at an average bond distance of 1.50 (1) Å.
The average stacking height of the parallel aromatic layers and the average diameter of the aromatic
layers are estimated to be 7.58 Å and 4.86 Å, respectively. For this coal, the average number of
stacking layers and the average number of atoms per layer are estimated to be 2 and 8, respectively.
In addition, the Gamma band is observed at a d value of 4.42 Å.
