Dear all Our axis control board (B 104) on our Bruker D8 is shot. I've replaced all the components I could see were burned out but needless to say it still doesn't work. Replacements are not commonplace (something about rocking horses springs to mind). Does anyone in the community just happen

Title: Re: diffraction patterns or spectra Dear Brian, to me spectroscopy sounds as a technique were an energy spectrum is used, i.e. the light of different energies has a different absorption coefficient (IR), or there is a different energy transfer for a fixed wavelength (Raman, INS, IXS).

Dear Lubo, Yes, I agree, the original work just means spread. But the contemporary use implies a more complicated meaning. However, it is not strict, at the level of feelings, not definitions. I am putting this query back to the list since it might be interesting to some people. Have a nice

Hello Yaro, I think that your view is correct, but if want to play with details, the energy dispersive diffraction like ToF can be called spectroscopy. From Wikipedia (it's sometimes useful): Spectroscopy was originally the study of the interaction between radiation and matter as a function
