###### The absorption spectrum for benzene in Fig. 14.8 shows maxima at about $180,200,$ and $250 \mathrm{nm} .$ Estimate the integrated absorption coefficients using $\epsilon_{\max }$ and $\Delta \tilde{\nu}_{1 / 2}$ and assuming that the width at half-maximum is $5000 \mathrm{cm}^{-1}$ in each case. What are the three oscillator strengths? (See Example 14.7 .)
