ChemApp

ChemApp is a software library that contains code that can be run by calling it from an application that you create. Since it is a library, ChemApp cannot be run by itself. You need to create an application (write a program) to call its functions.

The ChemApp library contains a set of 75 functions, all of which have a name that starts with the letters tq. We refer to this set of functions as ChemApp’s basic API. An API is a set of components like functions that programmers can use to call the library when they develop applications. As you use ChemApp for Python to write programs to do thermochemical calculations, you can therefore use ChemApp’s basic API, or one of the other APIs provided within ChemApp for Python.

GTT-Technologies released three different editions of ChemApp, namely Development, Redistributable, and Light. The Development edition is intended for people developing new applications with ChemApp, and the Redistributable edition for packaging and distributing applications that were developed with the Developer edition. The Light edition is provided free of charge for demonstration purposes, but has limited functionality. ChemApp for Python is intended to be a development tool, and is only provided in Development and Light editions.
