Question

SYMMETRY!

Answer 1

Are you referring to the point group and it's irreducible representation?

Answer 2

yes point group and irreducible representation (: pls help me? @abb0t

Answer 3

You can use this to help you. It was given to me long ago, and it helped me.

Answer 4

i know about the point group the thing is, im confused what is the difference between symmetry operation and irreducible representation? or are they the same?

Answer 5

But tey are basically linear transformations that are done, as you can see when you see a character table.

As you may know, for an s-orbital, which is completely symmetrical, all transformations are equal, since it's a sphere.

Answer 6

hmm, i mean, like when my prof said S2 is i so its not a unique operation, something like that i guess?

Answer 7

like for octahedral, 6S6 is E? and 3S6 is i? but 5S6 is unique?

Answer 8

i think i am talking about symmetry operation and not irreducible representations sry! ;p im hoping that is there a table for those unique operations for each shape? or not?

Answer 9

Why don't you look at tha charater table for the cyclopentadienyl point group, that will actually give you ALL the information as well as it's irreducible represenations.

It's a hard concept to explain.

Answer 10

You can find them here: http://www.webqc.org/symmetrypointgroup-d5h.html

Answer 11

okay.. its a D5h , i see so that means the symmetry operation is the heading in the character table itself?

Answer 12

what does it mean by 2(C5)^2?

Answer 13

E = means they are degenerate.
