摘要: Abstract In this chapter the atomic pair distribution function (PDF) is defined. The equations are derived from basic scattering equations. full range of PDF related laid out and a brief history method presented. A number extensions to presented such as PDFs in higher dimensions compositionally resolved PDFs. Finally, theory behind some practical aspects presented, handling estimating errors application Nyquist-Shannon sampling theorem method.
