FORTRAN interface for code interoperability in quantum chemistry: the Q5Cost library
1Dipartimento di Chimica, Università di Ferrara, V. Borsari 46, I-44100 Ferrara, Italy.
Abstract:
Ab initio quantum-chemistry programs produce and use large amounts of data, which are usually stored on disk in the form of binary files. A FORTRAN library, named Q5Cost, has been designed and implemented in order to allow the storage of these data sets in a special data format built with the HDF5 technology. This data format allows the data to be represented as tree structures and is portable between different platforms and operating systems, making code interoperability and communication much easier. The libraries have been used to build many interfaces among different quantum chemistry codes, and the first scientific applications have been realized. This activity was carried out within the COST in Chemistry D23 project "MetaChem", in the Working Group "A meta-laboratory for code integration in ab initio methods".

Electronic Structure of Atoms
An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum numbers: n, l, ml, and...
