LSDA Keyword
Last Update:
12/31/2000
This method keyword request a Local Spin Density Approximation
calculation, using the Slater exchange functional and the VWN correlation
functional for the DFT calculation. It is equivalent to SVWN. Note that
LSDA is not uniquely defined in the literaure. In fact, many differing but
related methods are referred to using this term. Other programs offering an
LSDA method may use somewhat different functionals. For example, some implement
the functional specified by the Gaussian 98 SVWN5 keyword, while
others use a correlation functional of Perdew. While Gaussian 98 offers
this keyword for convenience, it is probably better practice to specify the
exact functional desired; see DFT Methods for full details on specifying
and using Density Functional Methods in Gaussian 98.
