Abstract
IVIChem is an integrative web environment for computational chemistry that can be accessed globally from any typical computer via the World Wide Web. It assists users all along the research pipeline by facilitating the introduction of molecular geometries, specification of options for a calculation, assembling input files, submission to the calculation queue, monitoring the status of calculations, and graphical analysis of results. IVIChem's graphical user interfaces considerably improve the usability of computational chemistry software in different areas of chemical modeling, and they enhance the performance of researchers by automating the analysis of results and the addition of further calculation packages.
