Tabular processor for X-ray diffractometry


The program RTP is intended for the specialists in the area of X-ray analysis of crystal materials in various directions of science and technology. It allows to calculate the crystal lattice parameters (lattice constants) for syngonies from cubic to triclinic and also allows to calculate the reflexes positions for known parameters and diffraction indices. In addition, it has an indexing feature — determination the indices using shuffle technique for lattices up to monoclinic with unknown parameters, if the assumptions of lattice type and possible limits on indices and parameters do exist.

Examples of calculations


The main archive contains the version of the program for Win32 console (RTP32.EXE, RTP.CHM, RTPWL.INI). Another archive includes the test examples, which contain the tables of diffraction lines of various samples or the data taken from PDF for calculation the parameters; examples are especially useful to understand the indexing process.
