Q91 · CSIR NET Chemistry, December 2012
Paper: CSIR NET December 2012 · Subject: Physical Chemistry · Chapter: Molecular Spectroscopy · Topic: Molecular Spectroscopy – General · Marks: 2 · Difficulty: Medium
The absorption spectrum of $\mathrm{O_2}$ shows a vibrational structure that becomes continuum at $56875\,\mathrm{cm^{-1}}$. At the continuum, it dissociates into one ground state atom ($\mathrm{O_g}$) and one excited state atom ($\mathrm{O_e}$). The energy difference between $\mathrm{O_e}$ and $\mathrm{O_g}$ is $15125\,\mathrm{cm^{-1}}$. The dissociation energy (in $\mathrm{cm^{-1}}$) of ground state of $\mathrm{O_2}$ is:
(a)56875/15125
(b)15125/56875
(c)7200
(d)41750
