Chapter 14, Problem 14.15E

Diatomic sulfur, ${\text{S}}_{\text{2}}$, was detected in the tail of Halley’s comet when it last approached Earth in $1985-86$. It has a bond length of $1.880\times {10}^{-10}\text{m}$. Calculate the value of $B$, in units of ${\text{cm}}^{-1}$ and $\text{J}$, for ${\text{S}}_{\text{2}}$.
