About

DifCal

Features
Read full description

Calculate diffraction angles for a particular crystal with a defined orientation matrix. New crystals can be added to the database. Energy/wavelength can be changed. Currently knows about 4-circle, Z-Axis and Theta-Theta diffractometers as well as 2-circle, powder and amorphous diffraction modes. Current crystals include silicon, diamond, GaAs, Muscovite (mica), graphite, many 3-5 and 2-6 crystals. There are separate screens for setting the crystal (or creating a new one), defining the orientation matrix, defining the diffractometer mode, and calculating either angles, given h,k,l, or hkl given a set of angles. With the larger screen of the iPad all the controls are visible on a single page.

Never find yourself missing your point-group-symmetry Character Tables from group theory again. The Character Table Viewer app is designed to offer students of Inorganic Chemistry, Quantum Mechanics, and Group Theory ‘at your fingertips’ access to more than 45 Character Tables for the most chemically relevant Symmetry Point Groups. The tables are easy to find and access with an intuitive and simple interface. They are crisp to read and contain all irreducible representations as well as classifications of relevant linear and binary functions important for understanding things like bonding or vibrational motions. You can customize a list of the ones you most commonly use. You can zoom in on the tables and even compare two side-by-side. This is a ‘must have’ app for advanced chemistry and physics students and researchers.
