Some times it is shift to higher angle and some time to lower angles... Why it happens

Ravishankar Bhat

This may be due to functionalization..... Please verify with FTIR Characterization...

i have recorded its FTIR, i want to know.. change in angle.. mean change in interplaner spacing of tubes.... can u tell me in the same direction..
