  2. The application program package Split (Split-operator method for modeling 1D multichannel quantum dynamics and, based on this, optical electronic transition spectra) is uploaded into the folder APPLICATIONS.
  3. In the application program package sPade (Padé approximants, in the folder APPLICATIONS), the new auxiliary program sPadeChk.m is included, aimed to check and ensure desirable analytic properties of the approximant being constructed.
  4. In the application program package fgHAM0-(FourierGrid1D) ((Mapped) Fourier Grid Method for the 1D multichannel Hamiltonian, in the folder APPLICATIONS), the bibliography contained in the manuals is updated.

September 04, 2022

  1. The application program package STQ (modeling of optical electronic transitions in a polyatomic molecule with quadratic potentials, including quadratic repulsion) is uploaded into the folder APPLICATIONS.

November 30, 2021

  1. The application program DunTerm (the Dunham series for ro-vibrational terms of diatomic molecules) is uploaded into the folder APPLICATIONS.
  2. The application program RKRs (the Rydberg-Klein-Rees (RKR) method for a construction of a diatomic potential from ro-vibrational terms of diatomic molecules) is uploaded into the folder APPLICATIONS.
  3. The main package Optimizer.zip (sourceforge.net) is partly corrected for better functionality with later versions of Octave.
  4. The package sPade.zip (sourceforge.net) (Padé approximants) is partly corrected for better functionality with later versions of Octave.
