What is Cn in quantum mechanics?

 

[atyy]

What is the context in which you saw this?

 

[Tooba Sohail]

I saw in derivation of "sudden approximation"

Be more specific. Cn is just a symbol that is highly context dependent. There is no standard meaning of Cn.

Ok

ι∅(t) = ∑Cne^iEnt/h

The equation contains a sum of terms indexed by the integer n, and n ranges from 1 to infinity.

Cn is the complex coefficient in term n.

You can see similar notation in http://lpsa.swarthmore.edu/Fourier/Series/ExFS.html
