Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Title of program: GROUP THEORY LATTICE DYNAMICS 2 Catalogue Id: ACMI_v2_0 [ACMM] Nature of problem The original version of the program symmetry-reduced the dynamical matrix characterizing lattice vibrations of solids, constructed symmetry coordinates which were labeled by the irreducible multiplier representationsof the group of the wavevector, and block-diagonalized the dynamical matrix. This improved version of the program allows one to calculate the symmetry properties of the external modes of vibration of molecular crystals, to generate the irreducible multiplier representation (IMR's), a ...
