In this video, I have shown how to analyze Selected Area Electron Diffraction (SAED) pattern using ImageJ software. Like my other videos, this is the only available video on the internet, which shows some very important and simple tricks for interpretation of the SAED pattern.
After watching this video, you will be able to calculate the following parameter from the SAED pattern:
1) 1/D (per nm)
2) 1/r (per nm)
3) r (nm)
4) d-spacing (Å)
5) Miller indices (hkl)
6) Indexing SAED pattern
If you have any questions, ask them in the comment section below. For more videos, please subscribe to NanoWorld. Thank you.

A few people are confused about the conversion of.......1/D nm-1 into 1/r. You need to divide the 1/D values by 2. The formula for the conversion is 1/r = 1/D × (L / λ) / 2. Where: 1/D is the reciprocal space measurement in the SAED pattern. L is the camera length of the TEM. λ is the wavelength of the electron beam. The reason for dividing by 2 is that the diffraction spots in a SAED pattern correspond to the scattering vector, which is defined as: q = 2π / d. Where d is the real-space interplanar spacing. Thank you in advance

Thank you for the tutorial, the math for converting 1/2r into 1/r may not be right. I think you are supposed to multiply not divide by 2. i.e 1/2r is a smaller value than 1/r. please check, thank you for the information

I think you are right, if 1/2r=n; then 1/r=2n. But then why it seems to be right when compared with the standard values in the card?

Excellent video, covered every aspect. I have one question kindly respond to clarify concept of the community. Right from the start, obtaining 1/2r, till matching d spacing you video is very coherent. However, to obtain 1/r (2nd column of the table) from 1/2r, instead of dividing it by 2 (which you did), should we not do the multiplication? i.e. 1/2r * 2 = 1/r

You are right, But his is not the mistake. The actual mistake is, I measured 2R but mistakenly labeled it as 1/2R in the first place and then use R instead of I/R. However, the method and calculation is accurate. But you need just to consider the 1/2R as 2R, 1/R as R.
