In metals the highest band (or bands) are very broad, since the spatial ranges of

the highest atomic levels are comparable to a lattice constant, and the

**tight**-**binding**approximation is then of doubtful validity. 3. Although the**tight**-**binding**wave ...

approximate molecular wave functions are used, the approximation to the

molecular levels being combined with the
