Same value of FWHM is possible for all peaks in one sample?

How two melting peaks in DSC of polypropylene can be merged into one crystallization peak?

The figure shows DSC cooling (blue) and 2nd heating (green) curves (step: 10 K/min) for a commercial sample supplied as Atactic Polypropylene (APP). The heating curve illustrates two major...

What techniques can I use to determine the miscibility of polymer blends?

The term miscibility refers to the single-phase state in thermodynamics. I do not mean the compatibility of different components. To determine the miscibility I know several techniques such as...

What do I do with DLS peaks that are from the buffer?

I'm looking at the aggregation of my protein sample using DLS. Unfortunately, my buffer (20mM HEPES) also results in a set of peaks. These are at approximately 1 and 1000 d.nm. The lowest peak...

How can I find a Raman spectrum wavenumber corresponding to what compound?

I have several Raman spectra with very distinct peaks at certain wavenumbers, such as 277, 359, 466, 583, 623, 686, and 795cm-1. How can I identify them to what compound(s)? The RRUFF and others...

Dear Loganathan Kulandaivel ,

in addition to the answers of Dalibor Matýsek and Nilay Maji please resolve the Scherrer equation*), which roughly relates the crystallite size, the peak width, the wavelength and the Bragg angle theta,

you will find:

ß ~ FWHM ~ 1/cos(theta).

For completenes; as a function of 2theta, as mentioned above, you will have:

ß ~ FWHW ~ 1/cos[(2theta)/2]

*) see for example: https://en.wikipedia.org/wiki/Scherrer_equation
