Dear all QE users, being a newbie in QE, shall i ask you for what can be used the D3.x program and what can i “see” with it? Is it necessary for obtaining the Raman spectra? Besides, i’d like to ask you how to obtain the output file from dynmat.x suitable for gnuplot. Thanks in advance, Tommaso Francese, Università Cò Foscari di Venezia
