The electronic structure of the YBa Cu O family is discussed, using cluster models embedded in the large ionic cage. 2 3 7 ลฝ . ลฝ . ลฝ . The 2p holes at O 1 , two different types of 3d holes, 3d at Cu 2 and 3d at Cu 1 , all have resulted from the p x 2yy 2 z 2yx 2 calculations and are consistent with
The present Raman study in quasi-one-dimensional CDW system, (TaSe~)91 and (NbSem)91, elucidates the existence of three CDW-related TO modes: the amplitude mode fr6m~the Kohn anomaly point and two TO modes coupled with it. The CDW transition in this system is theoretically treated by the model with
