    Abstract

    We report lattice dynamics calculations of La2CuO4 and YBa2Cu3O7 where the mode assignment is fully performed. It is found that frequencies of the in-plane bond streching O vibration mode phonons are much higher than those of the bond bending O vibration mode phonons in La2CuO4, while they are close in YBa2Cu3O7. The bond streching mode phonons and the bond bending mode phonons can couple to electrons near EF in YBa2Cu3O7 but the latter can not in La2CuO4.
