You can extract the lattice planes from de Broglie equation. The XRD pattern will provide the d(hkl) for all peaks. Once you have compiled all the numbers, multiple them all by a number that would allow all the d(hkl) values to approximate to an integer number. Then use matrix like calculation to find which planes each peak belongs to.

A multiplied value standing at 3.95 would mean 4 which can only correspond to the hkl plane 200. A value at 5.9 would mean 6 and correspond to the hkl plane 211. Remember that when using that method when multiple plane solutions are available, it is always the one with the lowest overall parameters that is right (for a value of 9, 221 and 300 is possible however the correct plane is 221).

@ning chacha, can you be more precise in your request? what is it you want to draw, simply the lattice planes? If so, take a standard unit cell i.e. a cube. use the origin with x=h, y=k and z=l. The 110 plane would be the area within the intersection of lines from x=1 to the origin, from x=1 to y=1 and from y=1 to the origin, thus representing a right-angle triangle on the base of the cube with the right-angle at its origin.

@Christophe Petit: Let me give you some d-spacing values which are the following:

10.95,9.92, 8.10, 7.51, 4.80, 4.4. Kindly tell me which will be the h,k,l value for these d-spacing.

Another one thing I want to know about that is, if the multiplied value is 8, then what will be its h,k,l value (220/202/022 taking as x, y, z)?

10.95 would correspond to 311, 9.92 to 310, 8.10 to 220 and so on

Thank you Petit.

Dear Klemm, I would like to know how I get hkl parameters by utilizing d spacing obtained from pxrd without knowing the point group of the system.
