Lattice instability of 2 H -TaSe 2 and 2 H -NbSe 2 is studied on the basis of the electronic band structure of these compounds obtained by a tight-binding fit to Mattheiss' band calculation. The wave number and mode dependences of the electron-lattice coupling matrix and the generalized electronic susceptibility are calculated. The results are discussed in connection with the lattice instability.
