The energy required for various electronic transitions follow the order
1
\(\sigma \rightarrow \sigma^{*}>\mathrm{n}-\sigma^{*}>\pi-\pi^{*}>\mathrm{n} \rightarrow \pi^{*}\)
2
\(\sigma \rightarrow \sigma^{*}>\mathrm{n} \rightarrow \pi^{*}>\mathrm{n}-\sigma^{*}>\mathrm{n}-\pi^{*}\)
3
\(\pi-\pi^{*}>\mathrm{n} \rightarrow \pi^{*}>\sigma \rightarrow \sigma^{*}>\mathrm{n}-\sigma^{*}\)
4
\(\mathrm{n} \rightarrow \pi^{*}>\sigma \rightarrow \sigma^{*}>\mathrm{n}-\sigma^{*}>\pi-\pi^{*}\)
