LIFBASE is a free software program to chart the spectroscopy of diatomic molecules that is available as freeware from SRI International. The software is compatible with all 32-bit Windows versions. No support is available.
Comprehensive database capabilities
- Absolute rovibrational emission and absorption coefficients
- Variation of transition probabilities taking into account rovibrational wavefunctions and electronic transition moments
- Rotational radiative lifetimes and tabulated predissociation rates
- Frequencies for all rovibrational transitions
Spectral simulation
- Optical emission, absorption, excitation laser-induced fluorescence
- Thermal and non-thermal population distributions
- Line broadening
- Interactive change of simulation parameters
- Graphic interface
The current release covers these molecules and electronic bands:
- OH (A-X), OD (A-X)
- NO (A-X, B-X,C-X, D-X)
- CH (A-X, B-X, C-X)
- CN (B-X)
- CF (A-X, B-X)
- SiH (A-X)
- N2+ (B-X
