The spin orbit interaction splitting of a level corresponding to n=2 and l=1 of hydrogen atom -
\mathrm{\Delta T=5.84 \frac{2^4}{n^3 l(l+1)} \mathrm{cm}^{-1} }
\mathrm{Here, n=2, l=1 and z=1 (for \, \, hydrogen \, \, atom) . }
\mathrm{\therefore \Delta T=5.84\left(\frac{1}{2^3 \times 1 \times 2}\right)=0.365 \mathrm{~cm}^{-1} Ans. }
