2. Moving molecule structure identification is tough so we need to fix them by using Crystallization
Moving molecules
In moving molecules capterization is
Tedious
Fixed Sample: Defined Capture
3. X-Ray on Crystals
X-Ray waves Crystals
+
DNA
X-Rays on Crystal (carries Protein or DNA sample) causes diffraction, angle diffraction determines the
structure.
Based on the samples the diffraction may varies (consider the each side of cubes as a plane), X- Rays on the
planes shows some reflection that detected by the detector.
Data of diffraction help us to identify the molecular structure.
Reflection and diffraction are same.
4. Angle of Diffraction
Intensity of the spot directly proportional to
the electron present
High density of el- directly proportional to the
molecule occupy
