Additional Description

Abstract

The utilization of the reciprocal lattice and various methods or techniques, made possible through this lattice's use, will be explained in this Thesis [sic].

In general, these techniques can be classified into two common routines in which one is associated with the symmetrical structures (orthorhombic, hexagonal, tetragonal) and the other with the more complicated structures (monoclinic or triclinc).

The first routine is to take the differences between the data in reciprocal space and then search for those with the highest frequency of occurence. These most recurrent differences are put into the equation for the structure in question to see if they can regenerate the data within some degree of accuracy.

The second routine concerns the use of vector relationships in reciprocal space through which an expression for the interaxial angles and the lattice spacing a, b and c can be solved for.

These techniques were used on a sample of amorphous material at 380 degrees centigrade with the result that a tetragonal structure was discovered. The structure was able to match the data to or within the third decimal place.
