PPT-How to determine heavy atom coordinates from a difference Patterson map.

An outline Basic concepts If we observe a difference Patterson peak with coordinates uvw we learn that two atoms in the crystal are related by a vector with length u along x a length v along y and a length w along z In other words the vector relating two atoms in the crystal has the magnitude and direction of a vector drawn from 000 to . Do not enter during or immediately after heavy rain Take two torches per person and spare batteries Both 396580 a head torch and a hand held torch are recommended Always leave your trip intentions return time planned 396580 route party numbers etc w It is important to remember that expressions for the operations of vector analysis are different in di64256erent coordinates Here we give explicit formulae for cylindrical and spherical coordinates 1 Cylindrical Coordinates In cylindrical coordinate ?.
