Notations:

All numerical values are reported in a.u. (e=hbar=me=1).
The Cn coefficient has the dimension Energy x Lengthn.

Due to the limitations of the HTML language in handling the Greek alphabet, the diatomic electronic state symmetries are denoted by uppercase Roman letters: S for Sigma, P for Pi, and D for Delta. For example, 1,3Sg,u should be read: singlet Sigma gerade or triplet Sigma ungerade symmetries.

Typically, the numerical values are reported in the form nn(mm)[ee] which should be read as nn plus or minus mm times ten to the power ee. Both (mm) and [ee] are optional.

Manifesto:

This is a database featuring numerical and experimental values for dispersion coefficients of alkali-metal dimers obtained over the years. It is meant to provide a convenient reference for anyone to access.
The database is organized in three hierarchical levels. For each alkali-metal dimers there is a table containing values for dispersion coefficients for different asymptotes. For each asymptote and symmetry there is a list of references and alternative results for the dispersion coefficients. If you are aware about other published results for the dispersion coefficients of alkali-metal dimers which are not yet included in this database, please send a short message to alkali-metal@spin3.physics.gatech.edu. Please also direct your comments to the same address . They are welcome.

Currently, this database is maintained by Dr. Mircea Marinescu mmarines@spin3.physics.gatech.edu.
