Chemissian v4.01: A Powerful Software for Analyzing Molecular Spectra
Chemissian is a software that allows users to analyze the electronic structure and spectra of molecules. It can handle various types of calculations, such as Hartree-Fock, Kohn-Sham, natural transition orbitals, density maps, and more. Chemissian can also compare calculated and experimental spectra on the same plot, making it easier to interpret the results.
The latest version of Chemissian, v4.01, has some new features and improvements that make it even more useful for researchers and students. Some of these features are:
ED-EAT: A new method for estimating the excitation energies and oscillator strengths of transitions between excited states. This method can be applied to any type of orbitals, such as natural transition orbitals or configuration interaction singles.
Improved visualization: Chemissian can now display molecular orbitals and density maps in 3D, with different color schemes and transparency options. Users can also rotate, zoom, and export the images in various formats.
Enhanced performance: Chemissian has been optimized to run faster and use less memory, especially for large molecules and complex calculations.
Chemissian v4.01 is available for download from the official website[^1^]. Users can also find tutorials, examples, and support on the website.
Chemissian is a user-friendly software that has a simple and intuitive interface. Users can easily load their input files, choose the type of calculation they want to perform, and view the results in various formats. Chemissian can also generate input files for other popular quantum chemistry programs, such as Gaussian, ORCA, and GAMESS.
Chemissian is a versatile software that can handle different types of molecules and systems, such as organic, inorganic, metal complexes, clusters, and solids. Chemissian can also analyze different types of spectra, such as UV-VIS, IR, Raman, NMR, EPR, and X-ray. Chemissian can help users to understand the electronic structure and properties of their molecules and systems.
Chemissian is a valuable tool for researchers and students who are interested in molecular spectroscopy and quantum chemistry. Chemissian can help them to explore the relationship between the structure and spectra of molecules, to identify the nature and origin of the transitions, to assign the peaks and bands in the spectra, and to compare the theoretical and experimental results.
