YBCO Phonon Frequency: Hole Doping .2, 75-70°K @ 70°K

[Strange_matter]

I was hoping someone could tell me the phonon frequency of the electrons for YBCO with hole doping of about .2 and a critical temperature of around 75-70°K at about 70°K. An answer in Hz would be preferred, or failing that, in cm^-1 with the wave speed. Also, might the Kohn anomaly influence the frequency?

The critical temperature of the YBCO is about 70-75°K, and I want to know what the phonon frequency is. I found an article that might say that it's about 345cm^-1, but I need it to be in Hz, and I am concerned that this Kohn anomaly might change the frequency. Here is a link to the article and a picture of the table I am looking at: http://www.nature.com/nmat/journal/v11/n8/full/nmat3378.html
