hi all 

do anyone how to separate the following complex number into 
real part and imaginary part?
1/2 (Kab + Kba + R2a + 
   R2b - \[ImaginaryI] \[CapitalOmega]a - \[ImaginaryI] \
\[CapitalOmega]b + 
   Sqrt[(-Kab - Kba - R2a - 
      R2b + \[ImaginaryI] \[CapitalOmega]a + \[ImaginaryI] \
\[CapitalOmega]b)^2 - 
    4 (Kba R2a + Kab R2b + 
       R2a R2b - \[ImaginaryI] Kba \[CapitalOmega]a - \[ImaginaryI] \
R2b \[CapitalOmega]a - \[ImaginaryI] Kab \[CapitalOmega]b - \
\[ImaginaryI] R2a \[CapitalOmega]b - \[CapitalOmega]a \
\[CapitalOmega]b)])

thanks
