the meaning of volume fration in OLIGOMER

#1 Post by zhuwenkai » 2018.10.21 16:42

Hi, all
I have some questions about volume fration in OLIGOMER. Is volume fraction equal to number fraction or molar fraction? Considering a multicomponent of mixture ,A, B and AB.

The form factors are obtained from pdbs and no scale was performed. The volume fraction given by OLIGOMER is 0.25, 0.25, 0.5 It is supposed that AB is twice bigger than A and B in terms of

volume. Can I consider that the three components have same number fraction or molar fraction? I guess i can't, please help me figure out and tell me why. Thanks in advance.


Cheers,

Wen-Kai Zhu
