Hi guys., i wanna discuss about Raman spectroscopy, i have ever read that when electric field applied along the axis is approximately twice as large as that induced by the same field applied across the axis?? can you tell me why ??

Question

chmvijay · Answer

to create polrizability in the molecule i think!!!

anonymous · Answer

i mean the axis of molecule

anonymous · Answer

yes of course..,  but why the greatest polarizability in these molecules is achieved when the electric field is applied parallel to the molecule rather than perpendicular to the molecule. ??

anonymous · Answer

I can't imagine ..,

anonymous · Answer

have you idea @chmvijay  ??

chmvijay · Answer

humnnn i have to think over it ! let u know after some time

anonymous · Answer

i'm sorry., but would you like to explain this figure http://photonicswiki.org/images/thumb/9/91/Anisotropic_polar.JPG/800px-Anisotropic_polar.JPG it's anisotropic polarizability..,

chmvijay · Answer

it is related to the something molecular bond axis and the electric field axis

chmvijay · Answer

if the molecular axis and the electric field  parallel then only polarizability in molecule can be created i think!!!

anonymous · Answer

do u know what is the reason??

chmvijay · Answer

ok lket me read and come back to you right now i dont no clearly ok!!

anonymous · Answer

ok..., thank you so much :)

anonymous · Answer

@chmvijay look at this one , Xue et al using "Average Polarization theory" to make a model for effective thermal conductivity of nanoﬂuids..,

anonymous · Answer

I'm making timeline ideas for this paper.., can you help me?

chmvijay · Answer

yaa let me read and come back

anonymous · Answer

ok

chmvijay · Answer

how this si related to raman spectroscopy

anonymous · Answer

no.., it's different assignment..,

chmvijay · Answer

what i have to do in this assigmenemrnt its more phys and maths and less chemistry
